I applied online. The process took 2 weeks.

I have given 2 technical rounds in total so far. My 1st round went pretty decent; I would say it was good overall. It was taken for 1 hour, in which questions related to my domain were asked as well as coding.

Later, the tech recruiter or HR calls me and tells me that my DSA is weak, but she scheduled a second round for me and advised me to improve my skills on that. In the second round, the interview went amazing, and I was hoping for a positive response. The HR calls me again after a few days and gives me a 10-long-minutes lecture about how my programming skills are still lacking behind and I need to improve, and the comment she passed was really negative and not a good criticism. She says that my DSA and problem-solving skills don't meet "the standard of the industry", but says that my third round is also scheduled. My only concern is if I am lacking so much behind, why are they selecting me further.

The topics were OOPs, DSA basics, MVC, UI, and the previous project.
