Interview Preparation Tips
1. The position you have applied for can help you assess the questions in most of the times .
For example
- In my case I applied for a systems Engineer position which requires a basic knowledge of programming and good communication skills .
- In case If you have applied for a DSA of power programmer interviewer would definitely test your deeper understanding in programming and any other new Technologies
2. Be Prepared for an interview before the exam itself . We can expect few HR questions even before entering the interview panel room . So donot ignore such sure shot questions like
- self intro
- are you willing to relocate ( obviously Yes in many cases)
- shift related
- where do you see yourself after 5/10years
- strengths and weakness
- how are you handling your weakness
3. Never answer more than what's required .Be precise and crisp
If you don't know the ans just let the interviewer know that you are unaware of the topic and share well-known topics of yours
