Metaswitch Software Engineer Interview Questions
& Process

First, there was an online interview with math and puzzle questions, plus some coding in Ruby. Then, an in-person interview followed, featuring more puzzle/logical questions and a pseudo programming test, where we discussed the answers and the scalability of the solutions.

First there were some typical psychometric test problems, math problems. And then there was this blackjack problem, you needed to write a program for it. After that, a senior engineer will review the answers and discuss results with you. It was moderately hard, but the people are really nice.

The interview process involved a day of unannounced tests. One was a high IQ test, which seemed to be a justification for their arrogance. Another was a verbal reasoning test, and then there was a basic code review challenge. Following that, I had an interview with a developer who asked if I would want to work in finance, even though it wasn't mentioned on my CV. He seemed quite upset that he didn't work in finance and came across as aggressive and socially awkward. It was also very noticeable that the office was predominantly male, which was off-putting, and the women present seemed to be in low-level admin roles, which was also quite off-putting. They appear to have a fascination with maths graduates. The HR representative called me afterward to mention they had recently rejected a PhD Physics graduate from Oxford for not meeting their hiring bar, and she seemed to take delight in sharing this information.
