Altimetrik Sr. Software Engineer interview questions

I have given 3 interviews in the past 3 weeks. After clearing first round they shared a link for back ground verification process. That link was asking me to login via PAN card and EPFO/ITR password to verify your documents. My question is why the hell do I give my password to any third party website to verify my documents. It is like give me your password to check you are available in facebook or not something like that. You know what I am trying to convey here. After sharing my documents via mail, They had not schedule my interview for the second round.

There will be three round of interview - L1 - In this round basically focus on Basic tech question along with data-structure. L2 round will be the Java advance section like Threads, concurrency, Spring boot & Microservice.
