Hi all,

My exp: 5.10 (Java)
Current Location: Bangalore

Round 1 & Round 2: Easy to medium level DSA questions (dont remember but pretty solvable)
Feedback: Positive (no negative details)

Round 3: Interviewer grilled me on technical topics.

1. He started with Databases - I aforementioned I barely worked at Database level, written basic queries to fetch data - he skipped the topic completely (feedback was candidate lacked DB knowledge)
2. Then he asked question like producer and consumer where producer produces events (timestamp, userid, msg) in unordered way. Consumer consumes them and once the batch reaches 100size sorts and prints. I gave him working solution (feedback was solution was incomplete but acceptable)
3. When a user hits 100 requests at a time what happens on the server, how they are processed in your springboot application? (please share your answers)
4. How do you limit amount of data size in request? I said I use page no and size in the request. He asked me to show it and I have shown.
5. What measures will you take for the scenarios when the service you call not responds for some reason like timeout? I said Circuit breaker pattern
6. Grilled me about Circuit breaker - How it helps? You can use error response 500 to understand that service failed but why do you need circuit breaker etc. I have answered the advantages (please share your answers too)
7. Where you deployed your services? I used different platforms - OCP, Cloud like AWS etc

Overall feedback - just average
(Candidate has good problem solving skills. Technology is poor - answered all but barely scratched the surface etc.)

My experience is that the cross questions were unclear. He asked on a very high level which are very difficult for me to interpret what was he expecting as an answer.

Have HM round scheduled tomorrow. Any suggestions on how to do in that round are welcome. My recruiter mentioned if HM goes well, most likely will get offer.

I will keep you posted

Update:
Round 4: HM Round
He politely spoke throughout the interview.
Started off with a coding problem - min swaps to balance parenthesis. I did not solve the problem before but know using stack to check balanced/unbalanced parenthesis.
I maintained a count of unbalanced ones but it did not give min swaps.
Then I digged with other examples and found the logic. Interviewer also had participated in solving the problem. Finally got the solution.
Other topics:-
Microservices and REST API - what are they and differences?
Authentication
Statelessness
Talk about previous project with Microservices

Feed back: Positive (not received detailed feedback yet)

Edit: Forgot to mention that there was another HM round after Round 1 & 2. Interviewer asked some managerial questions like how do you know and why do you want to join etc. Then a palindromic substring question and newsfeed systemdesign. I was not able to solve coding question completely. We discussed the design on high level where she asked a few questions and I clarified.
But the feedback was design not good, can consider for IC2.
