Current Employer: Product based MNC
YOE: 5+

Application Process: Recruiter reached out on LinkedIn
Interview Process
Round 1: Online Assessment on CodeSignal
2 DSA Questions based on array, String, HashMap, Stack
Question1: String manipulation with Stack(Easy)
Question2: https://leetcode.com/problems/number-of-adjacent-elements-with-the-same-color (Same question with different constraints)
Time : 70 mins

Round 2:
General tech knowledge
Past projects(most challenging)
Monolith vs Microservices
Sql vs NoSQL
ACID properties in detail
One scenario based question:- How to handle multiple pay click by user in Payment System(Gave Idempotency key + Rate Limitting based solution)
Time : 45 mins

Round 3(Loop):
DSA :
Sync vs Async Programming(how async wait works internally)
Generators in Python
JIT compilation in Java(working in depth)
SkipList Data structure(working + time complexity of insert, delete)
Bloom Filter(how to delete element from BF, told we can't, follow-up:- which DS similar to Bloom Filter supports deletion)
Bellman-Ford Algorithm(working and Time Complexity)

One DSA question(Leetcode Hard), working code was expected in 20 mints:- https://leetcode.com/problems/add-edges-to-make-degrees-of-all-nodes-even/
Time : 60 mins

Verdict: Rejected
DSA round didn't went well, was not able to answer most of the questions(I mean who will read about Cuckoo Filter(same as Bloom filter with deletion capability)). Also 20 mints for a Leetcode Hard(may be a CM on Codeforces can solve).

One day after the DSA round, I got the rejection mail, no feedback was given as it's against their policy.

Suggestions:
Keep resume updated with skills you are well versed with(having Node.Js and Python from my past experience backfired me as there were multiple questions on those skills)

I had mentioned(in my resume) that I've done Competivie programming in past and I think that was the reason he asked me a Leetcode Hard problem(20 mints). Don't mention such thing if you are out of touch from CP
