The HR sent an invite through Naukri.com.

I went there and found that they had invited way more people than they could handle.

They took a written round first, which included some algorithmic problems. After that, they asked us to wait, and we kept waiting for three hours, only to find out that these guys were having breakfast, which was the reason for the delay.

They called for the first F2F (Face-to-Face) round, which was nothing like it. A guy came, gave a problem, and asked me to solve it, then went away. If they wanted me to solve these problems only, why have an F2F round? Why not just put all the bloody problems in the written test?

F2F interviews are conducted so that a candidate can be judged on their experience with technologies. If you want a bloody "matrix and pattern printer," why don't you mention it in the job description (JD)?

The HR had mentioned JavaScript, Java, Angular, blah blah, and not a single question was asked from these.

Print a matrix in a spiral. Find a name in any line in a 2D array of characters. Recursively check for a string palindrome.
