HR called me, and an interview was scheduled for two days later, on a weekday.

There were five rounds conducted on the same day, spanning seven hours.

The first three rounds were technical, with questions covering Object-Oriented Design, problem-solving, and Java internals. The last two rounds were with a Manager and the Director, focusing primarily on behavioral questions.

HR mentioned they would provide feedback within a couple of days, but none was received.

Although I couldn't answer a couple of questions, the interview had gone well overall. When I followed up with HR after two days, they stated there would be an internal meeting the following day, after which feedback could be provided. However, even two weeks after that, there was still no feedback.

I have no complaints about the process itself, but their lack of a feedback system is quite rare and not ideal.

Algorithmic questions on heaps, trees, and arrays.
