Pointwise interview questions

Submitted an application. Was contacted within 3 days by the recruiting team, and had a 30-minute phone interview within the next 3 days. Contacted about the offer 2 days after the interview.

They asked me many questions about my Resume, and ask me how I do my research, what kinds of methods I used. Other than it, they also asked about the programming background I have. I say that I have some basic background. Few days later I received an email that they say this position is not fit for me.
