As an investment banking summer intern, you’re stepping into a world where professionalism and etiquette are paramount. In this environment, your behavior and communication skills can make or break your chances of securing a full-time offer. We’ve compiled a list of summer intern etiquette tips to help you navigate the office, impress your colleagues, and avoid common pitfalls.
- Summer Intern Cell Phone Etiquette
- Set your phone to vibrate or silent mode and check it only during breaks or after work.
- Resist the temptation to text or browse social media at your desk; your teammates and managers will notice.
- During training sessions or job shadowing, keep your phone out of sight to show respect for the person guiding you.
- Handle Personal Calls and Music with Care
- Most investment banking offices have an open floor plan, so taking personal calls at your desk is a no-go.
- If you must take a call, find a private space, such as a conference room or step outside the building.
- Listening to music while working depends on your manager’s preferences, so have that conversation early on.
- Be Mindful of Your Internet Usage
- Many firms block social networking and personal email sites to minimize distractions.
- Using your personal device to circumvent these restrictions is not a smart move.
- Limit your personal internet use to short breaks or lunchtime, and always prioritize your work.
- Shine in Meetings and Conference Calls
- Never bring your personal phone to a meeting with senior managers; it shows a lack of engagement.
- Come prepared with questions, take notes, and actively participate in the discussion.
- During conference calls, ensure your name is properly displayed, mute yourself when not speaking, and maintain eye contact with the camera if it’s a video call.
- Craft Professional Emails and Instant Messages
- Double-check the recipient’s name, proofread for spelling and grammar errors, and ensure your tone is professional.
- Keep messages concise and avoid using emojis or gifs in work-related communications.
- Remember, emails are permanent records that can be accessed even if deleted, so always maintain a professional demeanor.
- Be Aware of Your Surroundings
- When traveling in groups or chatting in common areas, keep conversations professional and appropriate.
- Avoid controversial topics or language that could be overheard by colleagues or superiors.
- Be mindful of office pet peeves, such as cooking pungent foods in the communal microwave or improperly using the water cooler.
- Prioritize Self-Care and Presentation
- Get enough sleep to maintain your focus and productivity; falling asleep at your desk is a surefire way to damage your reputation.
- Dress the part, arrive on time, and come prepared to show that you’re taking your internship seriously.
- Take initiative, help your peers, and maintain a positive attitude to enhance your personal brand.
The Bottom Line: As an investment banking summer intern, you’re laying the foundation for your future career. By mastering these etiquette essentials, you’ll demonstrate your professionalism, respect for your colleagues, and commitment to excellence. Remember, your actions and communication skills are just as important as your technical abilities in this competitive industry. Embrace these unwritten rules, and you’ll be well on your way to making a lasting, positive impression.
When Things Don’t Go as Planned
Despite your best efforts, not every internship ends with a return offer. As your summer internship concludes, you’ll receive one of three outcomes: Offer, No Offer, or Hold. If you don’t receive an offer, it’s natural to feel disappointed, but this doesn’t signal the end of your banking aspirations.
