Airbnb Software Engineer interview questions

Have had two interactions with two separate recruiters, six months apart. Neither could be bothered to call me within half an hour of the scheduled time, or cancel, or reschedule, on multiple calls, which makes it very hard to fit an interview into a busy day. Be prepared to waste time sitting by the phone if you want the privilege of interviewing here. Also, if you are job searching while still employed, be prepared to get calls an hour or two later, after your lunch break you scheduled the call for has ended.
