I've been interviewing for the past month or so and its been terrible from many perspectives; I'm fine with the interviews content-wise (silly questions excluded), but the entire process is such a time-sink. I have a current position (full-time job) and really just don't have time for (with each company) 30 minutes of emailing, an hour phone call, a short coffee meeting, an offline coding challenge and then a 3 to 6 hour on-site interview. Additionally the weather in Boston has been dreadful, and getting to places just takes longer than normal. Again, I already have a full-time position, and finding ways to schedule these into my work day just doesn't really work well. The interviews I've had have gone well, but I'm counting down the days until I find the perfect company that makes me an offer that I like, because the entire process is just eating into my life.
