I have applied in 2 startups both in 3D printing domain. One consist of young and energetic graduates working on some projects related to it and also involved in selling a paid on too. But on the other hand the 2nd one consist of experienced entrepreneurs working on a single project related to 3D Scanning and printing, its unpaid. Please help on how to select, what main points should i look.
It depends on what you want. Are you looking for experience? To pick a winning horse? The important part of any job decision is to decide on what you want. This sounds basic, but for every job decision I've ever made I started with a statement of what I want and then did a pro/con list. I assigned a value to each item and derived a score. It's really easy to get caught up in trying to make the "right choice". I don't regret any of my job decisions, so it's worked for me. Might work for you too.
