I applied online.

There were two technical rounds of interviews, followed by a managerial round and an HR round. A total of four rounds are conducted for the final offer letter.

• 1st round: Included a programming question about printing prime numbers in a given range. You should try to do it in minimum time complexity as it is an easy question. The round also covered OOP concepts in Java, API design structure, and its types.
• 2nd round: Followed by a programming question about printing the longest palindromic substring. It was followed by some API-related questions and designing an ATM machine code from scratch that satisfies all boundary cases.
• 3rd round: The managerial round in which they asked about your previous experience, the technology stack you have worked with, why you want to switch, and other topics.
• 4th round: The HR round in which they will ask about your past experience, the reason for switching, and finally your salary expectations.

Java OOPS, Data Structures & Algorithm, System Design, and API development/structure. There was 1 answer.
