1st Technical Screening round

• Number of island + 30 mins on on past projects + OS basics (process, threds, semaphore, mutex, PCB, TCB, heap, stack, networking basics)

Got a response after 8 days about onsite

Onsite rounds
1st Coding round

• question based on N-Array tree. I dont remember the exact question

2nd Coding + AI round

• Code snippet with 1 function to implement. It was related to topological sorting. Could say mix of course schedule like questions.
• The interviewer had 0 idea on how to conduct this round. ended up wasting my 20 mins to figure out which AI assist we are using. He was clueless and I felt this round deserves a re-do but unfortunately it wont be the case.

3rd System Design round

• Metrics aggregator, monitoring system

4th Host manager round

• Go through past projects
• Asked about projects I am proud of - follow ups on technologies and workflows in this
• Technical challenges I faced
• Design choices
• BQs
• at the end of the interview gave me something similar to System design question. How to migrate data from one Data centre to another (some conditions applied)

Overall a good experince. Let's see what happens.
