I applied online. The process took 3 days. I interviewed at Socialarc (Emeryville, CA)
Interview
Initial round of about 4 interviews, all in one setting. No phone interview ahead of time except a friendly call to see if you can come in. Friendly team, good questions, overall a good experience. Only downside is the location of the office is a little bit of a pain.
Interview questions [1]
Question 1
No difficult questions per se. Just be sure you're very versed in the social landscape.
