I was contacted by a recruiter for an interview and just attended the first telephonic interview.

The interview happened on a phone call, not on Google Hangouts or any platform with a collaborative editor where we could code or share our ideas.

I recall having a good technical discussion with the interviewer and hoping I would advance to the next round easily.

Then, I received a rejection email after several days of my follow-up.

All the questions were regarding my work experience. I explained in detail all the projects I worked on.

Then, he asked me questions on password management, such as how you store and validate passwords, what salt is, and how you would achieve security.
