A Week Before Your IB Start Date: Final Preparation Checklist

Introduction

The week before your investment banking start date represents a critical transition period. You have finished recruiting, completed any pre-start requirements, and now face the final countdown before your career begins. How you spend this week can meaningfully impact how smoothly your first days and weeks unfold.

This is not the time for intensive technical cramming. You will learn the job by doing it, and training programs exist specifically to bring you up to speed. Instead, this week should focus on practical preparation, mental readiness, and strategic groundwork that positions you to start strong and make excellent first impressions.

This checklist covers everything you should address in your final week: wardrobe and logistics, physical and mental preparation, light technical review, relationship groundwork, and setting up your life for the demanding schedule ahead. Completing these items ensures you walk in on day one confident, prepared, and ready to perform.

Your appearance on day one sets immediate impressions that persist. Overdressing slightly is far better than underdressing, and having your wardrobe fully prepared eliminates unnecessary stress.

Business Professional Attire

Traditional corporate dress code requiring dark suits, dress shirts, conservative ties, and polished leather shoes. This is the standard for investment banking, especially during your first weeks before learning your specific group's norms.

Confirm Your Day One Outfit

Plan exactly what you will wear on your first day. A dark suit in navy or charcoal gray with a white dress shirt and conservative tie represents the safest choice. Avoid black suits, which read as evening wear, and skip anything with bold patterns or bright colors.

Your outfit should be:

Do not leave any element to chance. Discovering a missing button or ill-fitting shirt on the morning of your first day creates avoidable stress.

Prepare Your Full Work Wardrobe

Beyond day one, ensure you have sufficient professional clothing for at least your first two weeks. You need enough options to avoid wearing identical outfits in close succession while learning what your specific group's dress code actually looks like.

Minimum wardrobe essentials include:

Popular analyst choices for suits include Suit Supply for quality at reasonable prices. For shoes, Cole Haan and Allen Edmonds offer durability and comfort without appearing flashy. Avoid luxury brands that might seem ostentatious; you never want to appear better dressed than senior bankers.

Get Everything Cleaned and Ready

Take all professional clothing to the dry cleaner early in the week so everything returns with time to spare. Polish your shoes, organize your closet, and ensure every item is immediately wearable without needing repairs or adjustments.

Administrative details handled in advance prevent minor issues from becoming distractions during your crucial first days.

Confirm All Start Details

Verify every logistical element of your first day:

Contact HR or your recruiting coordinator if any details remain unclear. Arriving uncertain about basic logistics creates unnecessary anxiety.

Test Your Commute

Complete a dry run of your commute at the actual time you will travel on day one. Morning rush hour patterns differ dramatically from other times, and discovering your commute takes 45 minutes rather than 25 minutes the morning of your first day creates problems.

If you are relocating for the job, allow extra buffer time for unfamiliar routes and potential navigation issues. Understanding where you will park, which subway exit to use, or how building security works eliminates day-one stress.

Set Up Your Living Situation

Your apartment or living space should be fully functional and organized before you start. Once the job begins, you will have minimal time and energy for domestic tasks. Complete these before day one:

Many analysts find that having a reliable dry cleaning service and easy meal solutions (meal delivery, prepared foods, nearby restaurants) becomes essential once long hours begin. Establish these systems now rather than scrambling to set them up when you are working 80-hour weeks.

Analyst Living Logistics

The practical systems and services that make life manageable during intense banking hours. This includes dry cleaning pickup/delivery, meal delivery apps, nearby late-night food options, and automated bill payments that run without requiring attention.

Prepare Your Work Bag

Assemble everything you might need for your first day and keep it ready:

Having everything prepared eliminates morning scrambling and ensures you arrive composed rather than frazzled. Pack your bag the night before so you can simply grab it and go.

The demands of investment banking require physical and mental reserves. Building these reserves during your final week pays dividends during the intense initial months.

Prioritize Sleep and Rest

Your final week should emphasize restoring your energy reserves. Once you start, sustained sleep deprivation becomes reality, so banking rest beforehand genuinely helps.

Aim for:

Walking into your first day well-rested helps you absorb information, make good impressions, and handle early challenges effectively. This may be your last chance for proper rest for several months.

Exercise and Physical Health

Get in the best physical condition possible before starting. Regular exercise becomes extremely difficult once 80-hour weeks begin, and baseline fitness helps you handle the physical demands of long hours and high stress.

Consider:

Many analysts find their fitness declines significantly during the first year. Starting from a strong baseline provides more runway before the decline becomes problematic. You may not have time to exercise regularly for months, so maximize your fitness now.

Mental Preparation and Mindset

Adopt the mindset that will serve you well as an analyst. You are entering as a humble learner whose job is absorbing knowledge, executing tasks excellently, and continuously improving. Your objective for the first two to three years is simply becoming more effective at the work.

Mentally prepare for:

The right mindset treats every task as an opportunity to demonstrate reliability and build trust. Analysts who approach work with this attitude advance faster and have better experiences than those who expect immediate excitement or recognition.

Master interview fundamentals: Even after starting, continue building technical knowledge with our 400+ question database available through our iOS app.

While intensive studying is unnecessary, a light technical refresher ensures concepts remain accessible when you encounter them on the job.

Technical Refresher

A quick review of fundamental concepts you already know, not learning new material. The goal is keeping existing knowledge easily accessible in your memory so you can apply it smoothly when needed during training and early work assignments.

Review Core Concepts

Spend a few hours reviewing fundamentals you will use constantly:

This is not about memorizing new material but keeping existing knowledge fresh. Flip through your notes, review key frameworks, and ensure concepts flow easily when called upon.

Our guides on linking the three financial statements and enterprise value versus equity value provide useful refreshers on concepts you will use daily.

Brush Up on Excel and PowerPoint

Your daily work will involve extensive time in Excel and PowerPoint. Ensure your keyboard shortcuts remain sharp and your general proficiency feels smooth:

Struggling with basic software operations in front of colleagues creates poor impressions. A quick refresher prevents this while consuming minimal time. Smooth Excel proficiency signals competence and preparation.

Review Any Pre-Start Materials

If your bank provided pre-start reading or online modules, ensure you have completed everything required and reviewed any optional materials at least briefly. Arriving having done the pre-work demonstrates professionalism and conscientiousness.

Some banks provide access to modeling courses or technical resources before your start date. Taking advantage of these resources shows initiative and helps you hit the ground running. Do not skip these materials, even if they seem basic. They often contain firm-specific terminology and frameworks you will need.

The relationships you build in your first weeks significantly impact your experience and opportunities. Some groundwork can begin before day one.

Connect With Your Incoming Class

If you have contact information for other analysts starting with you, reach out before day one. These peers become your closest colleagues and support network throughout your analyst years.

Consider:

Starting with established connections makes the first days less isolating and helps you integrate into the analyst class more quickly. Your analyst class will be your primary community for the next two to three years.

Reach Out to Recent Analysts

Second-year analysts at your bank possess invaluable practical knowledge about navigating your specific group and firm. If you have contacts from your internship or recruiting process, reach out before you start.

Questions to ask:

This intelligence helps you avoid common mistakes and focus on what actually matters for success in your specific environment. Second-year analysts remember what it was like being new and typically offer candid, practical advice you will not get from senior bankers.

Research Key People

Learn about the senior people you will work with before meeting them. Review their backgrounds on the firm website and LinkedIn, note any shared connections or interests, and understand their areas of focus.

For the staffer in particular, who controls project assignments, understanding their role and importance helps you approach this crucial relationship appropriately. Many successful analysts deliberately cultivate relationships with staffers early, knowing that favorable assignments accelerate development and future recruiting opportunities.

Understanding the group structure, key deal types, and recent transactions also helps you speak intelligently when senior bankers ask about your interests. For guidance on different banking groups and their focuses, review our investment banking groups explained guide.

Investment banking will consume most of your waking hours. Organizing your personal life before starting minimizes friction and distraction during your demanding first months.

Handle Outstanding Personal Tasks

Complete anything lingering on your personal to-do list:

Every unresolved task becomes a distraction competing for your limited non-work time. Clear the decks now so you can focus entirely on work when you start.

Set Up Support Systems

Identify how you will handle personal logistics once you lack time:

Having these systems established means you can focus on work without personal logistics creating problems. Many analysts underestimate how much basic life tasks compete for attention when you are chronically exhausted.

Communicate With Friends and Family

Have honest conversations with important people in your life about what to expect regarding your availability. Investment banking will significantly limit your social time, especially in the first year, and setting expectations prevents misunderstandings and hurt feelings.

Explain:

People who understand your situation in advance tend to be more supportive than those who feel blindsided by your sudden unavailability. Frame this as a temporary commitment to building your career, not a permanent lifestyle change.

Take Time for Yourself

Finally, use some of this final week to do things you enjoy. See friends, pursue hobbies, travel briefly if possible, or simply relax. You have worked hard to reach this point, and the intense period ahead will limit these opportunities.

This is not laziness but strategic recovery. Starting your career from a place of fulfillment and energy serves you better than starting depleted from last-minute cramming or anxiety. Enjoy this transition period because your life is about to become dramatically more structured and demanding.

To understand what comes after you accept your offer and how to prepare comprehensively, review our guide on what happens after accepting an IB offer.

Here is a suggested structure for your final week:

The week before your start date should focus on practical preparation rather than technical cramming. You will learn the job through training and doing the work itself.

Wardrobe preparation ensures you make excellent first impressions without morning-of stress. Dark suits, conservative shirts and ties, and quality shoes are essential. Have everything dry cleaned and ready to avoid last-minute scrambling.

Logistics and practical setup prevent minor issues from becoming distractions. Test your commute, organize your living space, and prepare your work bag in advance. Confirm all start details with HR.

Physical and mental preparation builds reserves for the demanding period ahead. Sleep well, exercise daily, and adopt the humble learner mindset that serves analysts well. Start from your strongest physical and mental condition.

Light technical review keeps concepts fresh without intensive studying. Focus on fundamentals and Excel proficiency rather than new material. Review any pre-start materials your bank provided.

Strategic relationship groundwork accelerates your integration. Connect with incoming classmates, seek advice from recent analysts, and research key people in your group including the staffer.

Personal life organization minimizes distractions once work begins. Handle outstanding tasks, establish support systems for meals and cleaning, and communicate with friends and family about your upcoming availability constraints.

The preparation you complete this week translates directly into confidence on day one. Walking in with your logistics handled, your appearance polished, and your mind rested allows you to focus entirely on learning, performing, and building relationships.

Remember that your first three months establish how people perceive you and your work. Quality and reliability matter more than speed. Taking your preparation seriously signals the same conscientiousness you will bring to your actual work.

You have earned this opportunity through significant effort. Now finish your preparation thoughtfully, enjoy your final days of freedom, and start your investment banking career ready to excel.
