Good To Know For Every BizTalk Developer

I keep getting questions from BizTalk beginners around how to master BizTalk and how to crack interviews, well the simple answer is - you gain command on any technology by practice(hands on experience), spending time on discovering what's in it and finally applying the gained knowledge in best possible way. But when you are beginner, you need some information around how to start, what should be the approach etc and considering this I have started Series of Interview with BizTalk Expert around the world with a belief that it will help lot of us (an answer for how to become master in BizTalk). And for how to crack Interviews, below are 275 questions which in my opinion, every BizTalk developer should be able to answer.

If you are beginner(experienced one too :) ), then I would ask you to go through the questions which a BizTalk developer can face during an interview and try to answer yourself(this process will help you to understand more), but you can surely check the answers - link to answers is at the end of Questions.
