In the programming world, we look for people who can self-teach. I learned 2 languages in school but only used 1 but I have used 15 languages in my career. There is nothing more useless than a coder who won’t learn. H1B’s have lots of schooling and experience that cannot be verified but they will often refuse to learn anything that won’t help their career track.
I have worked with people who would not learn things on their own. If the company did not pay for formal training, they wouldn’t attempt it.
