Had three tech rounds that spanned over two months.

Each round consisted of Java basics, Java multithreading, and Java DS program questions.

Qualified in each round.

Gave an HR interview.

Even prior to all these, I had a firm ask regarding my ECTC, but failed to get an offer later since the company couldn't provide it even after taking my documents.

Overall, a pure time waste.

They should be clear on the CTC a candidate asks for and what they can offer from the start to prevent this sort of loss.

Also, HR was unresponsive unless they needed a response.

Design a microservice for huge data, where one can get the data from the cloud.

I didn't proceed to complete this as I had no time to design it in half an hour.

After this, there was one data structure question on BST.
