Hyperface Software Developer Interview Questions and Answers

This was an OA round. The question was very verbal and had a lot of requirements. Need to understand and then design a proper data structure to maintain. Even the brute force solution took 1h30m to complete and time ran up. Topics: TreeMap, Priority Queue

Got invited for onsite interviews. There were 3 interview rounds planned for the day. Very exhausting process.
Round 2[a]: I was asked to design entire micro service - Offer Management System in 1h30m. This included actually understanding a page of requirements, coming up with LLD and preferably table schema. THIS HAS TO BE WORKING BY END OF 1H30M says the interviewer first thing into the interview. After sometime no one was around to clarify the questions; just left me at the desk.

Round 2[b]: This was LLD/DSA round. I don't know what the interviewer was expecting TBH. Asked to solve problem of inventory management; where items needs to be placed in shelves. Need to come up with algorithm if find() and place() method.

Round 2[c]: This was HLD round. Got asked about handling database locks and reverting transaction in micro service architecture with more than one DBs involved.

Now all of a sudden; HR next day says due to limited time and after discussion across panel [after 6 interviews - all cleared successfully]; we think that you lack some things and want to evaluate further!!! I was at my limit but thought okay let's give it a try. He says you need to prepare a PPT on some library called Bucket4j.


And after 2/3 days of preparation I gave the PPT to co-founder. All the questions answered properly. No feedback given at all after interview. And finally have been since ghosted. It has been 15 days since this; and I reach out to HR via WhatsApp - he says we will NOT move forward. And no further official communication.
