Was contacted by interviewer on LinkedIn. Since I live in Seattle, I was called onsite for 45 min preliminary round. HR received me and gave office tour. Then, I was introduced to interviewer. Interviewer was young and energetic . Interviewer asked me a question around binary tree and I was able to answer the question and write code quickly. Next day I was contacted by recruiter saying that they want to scheduled another interview before calling me onsite. This time I asked for phone interview. Second interviewer asked another question related to trees. I was able solve the problem and write code in 40 min. Later HR contacted me and said Interviewers are not happy with me. I'm not sure what they were expecting. HR said they couldn't tell me the reason for rejection due to legal reasons. It seems like they just want young engineers who can just code.

Took about a month altogether, which felt longer given the intensity of the process. Kicked off with a technical screening, followed by two rigorous coding interviews. The DSA question on binary tree vertical order traversal hit me hard at first, but then I recognized the prompt instantly — I had just worked through something similar on PracHub. The final round was focused on system design, and while I ended up receiving an offer, I ultimately declined it. Overall, a challenging experience that definitely sharpened my skills.
