I have attended the interview last month for the post of the software developer. The company is quite good with only 20-30 staff. The interview was of total 4-5 rounds. They conducted aptitude, program writing round, two technical round and the final was HR round. I cleared all the rounds and was hoping to get the job, but in the last round, the interviewer asked questions related to the topics which aren't mentioned in my resume and I wasn't able to answer those questions and was rejected. Seems like they purposely did so.

It was based on basics of rdbms, dsa, html/css, python programming, past projects and experiences as well as coding on paper and explaining my thought process and around the topics mentioned above.
