Hewlett Packard Enterprise

The interview process consisted of 3 rounds. The first round was a technical round where they asked me to reverse a linked list in a single pass, some OS questions, CN questions, pointer output questions, and some basic questions related to arrays,

Was not hired in spite of answering all questions. He asked me questions from aptitude, and I could answer all also, but still did not move to further rounds. I was not told why I was rejected for the role.

It had three rounds. One technical, one managerial, and one HR round. It went on for one full day. They just wanted to see how well we fit in the company. They were interested in Computer Networks more.
