Interview Preparation Tips

General Tips: It was challenging for me to get into this company. I was rejected around 10-11 times before i got placed in this company. So finding out the reason and to overcome it in the next company was the challenging task.
For getting into this company you should have the knowledge of OS, Database,Networks and OOP concepts. "Job profile was software developer.
The questions asked to me were related to OS concepts like deadlocks process and threads n all. From networks they asked me about the wifi drivers installed in your system. They asked about dynamic programming and they gave me one question to solve using dynamic programming. Then they asked me to write two more codes . From database they asked me about the errors which we will get if we do these things in the table. They asked me about the hashmap and how does it work and why it takes constant time in data retrieval. They asked me about the OOPs concepts and the virtual class implementation in detail. In short they asked me questions from every field."
Skill Tips: For the interviews karumanchi is the best book.
Presentation skills matters alot. No matter how much u know, presenating your knowledge in front of the interviewer matters alot. Speaking very fast during an interview may lead you to rejections (personal experience).
