Summary
I interviewed for an SDE 3 role at Safe Security, completed an intro call, a technical DSA round where I solved a Merge Intervals problem, and a high level design round designing Google Calendar, but was rejected.
How it went
Company: Safe Security Role: SDE 3
Current Org: Startup College: Tier-1 YOE: 8+ Current Comp: ~65L (Cash component) + ESOPs
Round 1 - Intro Call (20 min)
- Basic intro and past project discussions.
- AI/LLM concepts: What a token is, how tokenization works, and why models hallucinate.
- CS fundamentals: Difference between a process and a thread.
Round 2 - Technical / DSA
- Basic intro followed by a deep dive into one of my most challenging past projects.
- DSA Question: Merge Intervals.
Round 3 - HLD
- Task: Design Google Calendar.
- I came up with a design that covered most of the core functionality, but completely missed handling timezones.
- They also asked some questions around how LLMs work during this round.
- Self-reflection: I felt I was not able to frame my HLD effectively. Additionally, the interviewer was not participating actively or guiding the discussion, which made it harder to pivot when I missed key edge cases.
Verdict: Rejected.
