I applied through college or university. I interviewed at Capital One (Waterloo, ON)
Interview
I applied through my university. They asked about me and my projects. Then asked me what data structures would be used to implement an android app's two screens. Tried to answer despite not knowing Android. The interviewer gave very negative feedback and did not try to help me come to a good solution. He only kept shooting down possibly different implementations unless it was exactly what he wanted originally.
Interview questions [1]
Question 1
Given pictures of two views of an android app, design a data structure to make it.
Was not too difficult. three total interviews all on the same day back to back. technical one, behavioral one and a case which was more of just a debugging question
Expecting a challenging experience, I found the interview at Capital One to be intense, particularly during the system design section. The question on designing a rate limiter with a token bucket algorithm took me by surprise; mid-way through the problem, I realized it was very similar to a drill I’d practiced on prachub.com just days earlier. The technical rounds included several DSA questions, and the interviewers were thorough but supportive. Ultimately, I received an offer and happily accepted, feeling well-prepared despite the pressure.

Question 1
Design a rate limiter using a token bucket algorithm and discuss how it would handle bursty traffic and distributed deployments.
Recruiter screening to begin with. Then, technical discussion about java, spring boot, design pattern, small coding tasks and followed by design assessment for distributed systems. Finally, managerial round for the team fit
