Had a 30 minute phone interview with the London office. The interviewer said he would set up an in-person meeting for the following week and email me the details. Never got an email. I tried to follow up with him, only to get a response over a week later asking for my availability again, saying he had been out of the office. This exact email process repeated a couple times until I finally got ahold of him over the phone. Completely unprofessional, and this seems to be a company-wide practice, judging from other reviews. The interviewer said he'd look into it, and asked if I was interested in interviewing for a sales position in the company instead--I wasn't. I got a form email a day later saying the position was filled.
