Went through the Amazon SDE-2 interview loop recently.

Round 1 was supposed to be HLD, but it got rescheduled due to unavailablity of Interviewer and then just never happened.

Round 2 was DSA - Started with LP discussion for 20-30 mins and after that it was a hard DP problem.

Round 3 was more like LLD + general problem solving. Focus was on writing clean, maintainable code. Had LP questions for 20-30 mins and a good discussion on designing a rate limiter and its diffierent algorithms token bucket, fixed window, sliding window along with implmentation of one of them.

Round 4 started with ~10 mins of behavioral (LPs), then DSA:

• LCA variant
• LRU cache with TTL
  Implemented both and discussed time complexity.

Then came the final HLD round which was supposed to be happend

A day before my HLD round, got a call saying it’s cancelled. That was it. No explanation, no feedback. Later saw the portal updated to “no longer under consideration” — no email, nothing. I did my best in all three rounds

Not gonna lie, it’s a bit disappointing after putting in so much time and effort, and then not getting any feedback at all. But yeah, I’ll take it as a learning experience.
