Infosys .NET Developer interview questions

It was a weekend mass drive. There was one technical interview. They asked about security in api, solid principles, unit testing, extension methods. The interview was good and they rejected me because of expected salary.

I was interviewing in Infosys for one month. Sounds weird but true. On 16th July interview scheduled at 3pm IST. Asked all Database related questions and answered all. Then interviewer cancelled the panel as I am an individual contributor in a team and he wants a lead. Again scheduled an interview on 30th July and asked questions from database architecture and design for which I haven't applied and set status as Not selected. Then got automated call to set again an interview on 6th August at 9AM IST. But no interviewer joined at that time.
