Probably the worst interview process I have ever had. It started out with a quick response from a recruiter to setup the tech screen. Now I'm not a huge fan of being asked or asking technical questions that have real life implications, but that was the only question I was asked. The question was "Given a telephone write a program that generates all possible permutations of letter strings." Sounds easy... it's not. It also has nothing to do with the job that I would be preforming. I worked on the problem for 35 minutes then talked about some technical topics for another 10 minutes or so. It was extremely difficult understand the person performing the interview (thick accent and he had me on speaker phone). I never received a call after that. A month latter I got a survey to take about the experience. I let them know how I felt about the process. It was not a positive one.
