what is Technical round in IBM Interview?

Most IBM interview questions are said to not be technical in nature – and not at all if you don’t have a technical background. However, if you do have a technical degree or have indicated some technical ability on your written application, you may want to prepare for some technical questions so as not to be caught off guard.
Some previous IBM technical questions have been:
1.What are your technical skills?
2.What are the advantages of object-oriented programming?
3.What’s the difference between an abstract class and an interface?
The best way to prepare is to look carefully at the job description for information about what kinds of skills will be relevant to the role and find out as much as possible about them. If, when you get to the interview, you’re asked something you don’t know, be honest about it – the interviewer will know if you’re trying to blag it.
