Entrevista
Recruiter reached out to me. We had one intro interview in which I was given the actual application to fill out (Full-Stack Developer). After completing that, I received a take-home technical assessment (CodeSignal / 70min / 4Qs) to do within 2 weeks.
After passing, we scheduled our "Power Day" of interviews. Got a run-down with the recruiter which was nice, but would take it with a grain of salt because some of what was said misled me in my preparation.
Power Day consisted of 2 "Job Fit" Technical interviews, 1 Behavioral, 1 Case. There was a "calibrating interviewer" for the two technical interviews - one was screen-off with no participation, and the other was pretty engaged. The other two just had one interviewer.
1st Job Fit Technical: Systems design
2nd Job Fit Technical: 1 Easy/Med LeetCode problem
Behavioral: 3 Questions, pretty standard
Case: Surprisingly straight-forward, but also not what I expected.
Interviews were fair/easy with proper preparation, but had a negative experience with some of the interviewers who gave some sarcastic remarks.

4 rounds of interview including coding , design , case study, behavioral after clearing the code signal assesment. Coding was medium hard of 2 questions each. case study and system design was difficult.
This took a bit longer than expected, stretching over several weeks. The technical rounds were intense, featuring an LRU cache implementation and a problem on detecting duplicate transactions within a 60-second window. I was nervous at first, but it clicked for me when I realized I had practiced a similar approach on PracHub just days before. Unfortunately, I didn’t receive an offer in the end, but the experience was a solid learning opportunity. The behavioral questions felt straightforward, so I wish I had made a stronger impression in the technical segments.
