I was approached by the HR team regarding the Sr. Software Engineer position at Osmos.ai. Here’s a brief overview of my interview process:

🧮 Online Assessment

Received the OA link with a 48-hour deadline (1.5-hour test).
I completed it in about 20 minutes — it consisted of:

• 2 LeetCode Medium-level coding questions
• A few aptitude / DSA conceptual MCQs

💻 Technical Round (1 hour)

This was primarily a system coding round.
I was asked to design an LFU Cache and walk through a dry run.
The interviewer was engaging, and it was an enjoyable session.
We also discussed topics like database internals and query optimizations toward the end.

🏗️ System Design Round (1 hour)

I was asked to design a URL Shortener. I structured my approach well from the beginning — discussing edge cases, bottlenecks, and optimizations — and completed it within 30 minutes.

Then, the interviewer added a follow-up:
“How would you design Facebook’s Trending Posts section?”
I explained my thought process, trade-offs, and scaling considerations, and the discussion went smoothly.

Overall, the interviewer seemed quite satisfied with the solutions and reasoning.

🧠 Reflection

I was genuinely excited about the opportunity and gave it my best effort.
Even though I felt confident about my performance, I received an email later saying I didn’t fit the current requirements.
It was disappointing — especially after multiple rounds — but it’s part of the journey.

If anyone has suggestions or feedback, I’d be happy to hear them.

🏢 Company Review (Osmos.ai)

The interviewers were technically sound and discussions were fair and interactive.
However, the overall process felt inconsistent — communication wasn’t very transparent, and they can ghost or reject candidates abruptly after multiple rounds.

Happy Coding & Happy Cracking! 🚀
