Tips from the candidate
I’d suggest focusing on strong fundamentals, especially data structures and problem-solving. Be clear with your thought process while solving problems, as interviewers care a lot about how you approach a solution. Also, prepare a few solid examples from your past experience that show ownership and problem-solving. One thing that surprised me was the depth of follow-up questions, so be ready to justify your decisions and optimizations.
Company culture
The overall vibe felt professional yet approachable. Interviewers were attentive and gave enough space to think and explain, which made the interaction comfortable. It seemed like the team values clear thinking and ownership. I didn’t notice any major red flags; overall, the environment felt supportive but performance-driven.
