I have 4 years of experience in Java development with service-based MNCs.

The interview was average, with two online rounds focusing on aptitude and C.

The difficulty level of the C aptitude quiz was 2/5, and the general aptitude was 4/5 (where 5 is the hardest).

Following these two rounds, I had 4 technical interviews and 1 HR round, which lasted a full working day (approximately 8 hours, including lunch).

In the interviews, the focus was mainly on puzzles and problem-solving rather than programming.

As this is a Software Engineer (WBT profile), I was not asked to code or tested on my knowledge of Java/C languages.

I was asked to write standard, simple programs for linked lists, arrays, and string manipulation with minimal complexity (repeatedly instructed to reduce complexity to O(n)).

Apart from that, be prepared to write test cases for any functionality.

You will be asked 2-3 puzzles in each technical round, so be prepared.

P.S. This profile is a mixture of Black Box and White Box testing. If you have a testing background, this profile would be suitable.
