Infosys .NET Developer interview questions

Sent CV online and then was contacted by phone about an interview. After that they emailed details of the interview with directions etc. Interview process was as follows: Technical interview with two experts - First asked what I knew about the company and asked about my previous experience. Then general OOP questions: 1. Difference between an abstract class and an interface (and why use an abstract class) 2. Difference between method override and method overload. 3. Do I know how to write unit tests. 4. What release processes did I know about. 5. Which SDLP concepts did I know about (and probed when answered) 6. Functional vs Non functional requirements. After that came some .NET-specific questions: 1. Recursion 2. Collections 3. How to implement an interface 4. Why not to use a hash table. 5. DAO/ADO 6. SQL (I don't have much experience with SQL and I told them that so they didn't follow up with any further questions on it). 7. Releases to production. That ended the technical interview. After that it was just a 10-minute thing with the HR guy where he was basically just filling in a form. Interview on Saturday, got the job offer on Monday.
