The interview experience was a good one, though it took almost six weeks to receive the offer letter.

The concepts presented were somewhat new, particularly in how they were asked, which I really enjoyed.

1. Phone Interview: This was a 30-minute call with the hiring manager. They asked about basic concepts and company description, and assessed communication skills, which led me to the second round.

2. & 3. Onsite: The second and third rounds were conducted onsite, each lasting one hour. They assessed in-depth knowledge of SQL databases, RESTful services, WCF, security (vulnerabilities and mitigation strategies), Agile-Scrum, TDD, regular OOPS concepts, and some scenario-based questions related to past experience. They aimed to gauge confidence by asking challenging questions, but if you are solid on the concepts, you should be able to answer them.

Rule of Thumb: Do not get nervous; stay calm, and you should be able to answer all the questions. They will initially try to make you comfortable by asking easy questions, but do not get carried away by that.

I can't submit any specific questions, but if you are good with the above concepts, you should be good enough.

Also, get familiar with the AngularJS framework and testing frameworks.
