I have done lots of programming but in academic research constraints (Mostly scientific computations) I used C, C++, and Java. Now that I am sick of academia I want to join industry but it seems I need to prove myself by getting some certifications. I never used .net. My questions are: 1- Do you recommend Microsoft Certifications to secure a good Job? 2- Is MCAD good enough? 3- What timeframe I should be looking at to study and finish the MCAD certifiction? 4- What preparation resources do you recommend? Thank you in advance
