FinBox Interview Process - Campus Placement FinBox shortlisted 50+ resumes and conducted 3 interview rounds. Round 1: Resume Screening & Compatibility Started with casual conversation, then systematically verified every claim on my resume. Deep dive into internships with questions like how exactly did I do query optimization and how did I measure API improvements. Projects section was grilled with tech stack justifications - for example, why ConvexDB over standard DB and what if WebSockets didn't exist. They wanted to know the reasoning behind every technical decision. Round 2: Technical + System Design Offered choice between DSA or System Design. I said either, so he chose both. Spent significant time explaining projects with flow diagrams from GitHub repos. When he suspected AI-generated code, I had to re-code it live to prove understanding. Then came LLD questions: designed Google Authenticator workflow and URL shortener architecture. For DSA, live-coded LRU Cache in nvim and wrote LFU Cache pseudo-code. Discussed microservices, monitoring tools like Jaeger and Prometheus, and designed a banking system architecture. Interviewer's feedback emphasized checking if my understanding was shallow or deep, especially since my major isn't CS. Round 3: HR & Behavioral This round focused on situational questions, teamwork scenarios, and culture-fit assessment. The interviewer presented hypothetical cases and asked how I would handle them, what steps I would take, and what tradeoffs I would consider. We also discussed learnings beyond code and how I work with people. Midway through the conversation, she informed me that they believed I would be a great fit for their team and offered me the position. Key takeaway: They validated every resume claim through practical questions and live coding. Deep understanding mattered more.
