the worst interview I've ever done, they provided less than 30 min (about 22 minutes) for technical interview, first they asked to introduce my self and tell about the iOS experience and made some questions related to the project what kind of problem I had on my project, how I solved it, and how we can explain it in just a few minutes explaining a huge project architecture? I think they should provide at least 1 hour interview to the candidate, whit about 22 minutes you can't measure the candidates. If you are really a senior developer with more than 5 years of experience in multiples projects run away from this interview, you'll spend some time with a company that does not have a really interest in your experience.
