Some tips to keep in mind when preparing for the Stripe interview process are:
- Begin your prep early, at least 8-10 weeks before your interview. This will give you sufficient time to cover all the important concepts from an interview perspective.
- Don’t get too hassled if a question appears too complex. Questions that seem complex can be easy if read and understood correctly. So just re-read the question calmly and don’t forget to ask questions if you’re in doubt.
- Throughout the Stripe interview process, the interviewers are trying to understand your thought process. You can make it a lot easier for them by keeping your answers as clear and simple as possible.
- Think out loud while solving coding and design problems. This will give recruiters a window into your thoughts. Remember, the approach you take and how you articulate are key areas that will set you apart from the competition.
- When practicing for the interview, ensure that you also practice in pair programming format as in the technical screen sometimes, your interviewer will act as your pair.
- Follow the STAR method (Situation, Task, Action, and Result) when answering Stripe Behavioral interview questions. This will give recruiters adequate understanding of what you wish to express.
- If you have a problem understanding a question, clear any doubts that you might have beforehand. This is much better than making a mistake over a confusion later on.
The Stripe interview process can get quite intense and complex. But this doesn’t mean it isn’t crackable. You’ll need to keep at it and practice as many . One pro tip is to research the company thoroughly and dig up the questions they are most likely to ask you.
