I attended the career fair at college, after which I received an online test. The online test had 3 questions and 1 hour; it was moderately hard. Then, we were sent an email stating that team matching was being done and that if our resumes were selected, we would be contacted. This process itself took 6 weeks before I received a confirmation that a team had selected me.

There were 2 phone interviews back to back:

1. First Interview: Two people interviewed me, the manager and a team lead. The team lead asked me about everything on my resume. This round included both technical questions and system design.
2. Second Interview: There were 2 interviewers who gave me 2 coding questions to solve online.

Given a pre-order list of operations along with operands, we need to compute the result. We also need to handle error checks and follow object-oriented coding principles.

Example: +98*8.

Given an in-order list of operations along with operands, we need to compute the result. Was converting in-order operations to post-order operations a fundamental question?

As before, we need to handle error checks and follow object-oriented coding principles.
