I had two phone interviews, each with a different prospective supervisor. They were both very friendly, more-or-less casual, and asked normal interview questions. I was told that the decision would be made very soon, but waited another six weeks to learn I had not gotten the job.
I applied online. The process took 2 months. I interviewed at Yahoo in May 2015
Interview
I had a one-hour phone interview followed by a panel interview in person with members of various teams that I would work with. They followed up with me almost immediately after each interview, but there was a few weeks between each stage in the process (phone interview, in-person interview, offer).
Interview questions [1]
Question 1
They asked me why I was interested in the position. They were also interested in why I was interested in switching industries. They asked me to anticipate what the challenges of the job would be for me. They also gave me a hypothetical to see how I would handle a situation at work.
