The process began with a recruiter contacting me via LinkedIn, followed by a telephonic round. After clearing that, I attended a virtual onsite interview. The recruiters were very responsive, and I had positive interactions with everyone I spoke with. The entire process was well-structured and completed in approximately two weeks.

Telephonic Round: A medium-difficulty LeetCode question.

Virtual Onsite:

• Two technical coding rounds
• One system design round
• One round with the team lead
• One round with the product manager

1. The first coding round went very well.
2. In the second coding round, the interviewer seemed confused himself and struggled to explain the question clearly. To this day, I remain unclear about the question asked. The issue stemmed from the interviewer not having the question written down and reciting it from memory, which impacted my performance.
3. The system design question was challenging. I became confused at one point and was unable to provide a strong answer.
4. The rounds with the team lead and product manager went very well.

System Design: Design a system where you can submit a check by taking a photo from your phone. I was grilled on how you would ensure that the funds will be deposited once the check is cleared.
