I applied through a recruitment agency, and my profile was shortlisted for an in-person interview. According to the job description (JD), I was supposed to be tested on Data Structures (DS) and algorithms. However, when my first round started, the interviewer asked me about Java frameworks, stating they were specifically looking for someone with extensive experience in Java frameworks. I clearly told him I hadn't worked on Java frameworks. He then asked a couple of questions related to DS and algorithms.

I was pretty sure I wasn't the right fit for the role. After the first round, they made me wait there for three hours and scheduled a second round, which lasted only for ten minutes. Very easy questions were asked on linked lists and strings.

They then told me they would let me know in two to three days, and the response was negative, which I was expecting. The problem is, first of all, they didn't provide a proper JD. Secondly, after the first round, the panel was aware that I didn't fit their criteria, yet they still made me wait for three hours. It was a really horrible experience.
