Referred to interview here. Had a 30 minute call with the CEO, who said I would know if I moved on within 24h and that we just needed to have engineering take a look at and approve the resume. Reached out the next day and was advanced to the next round. Scheduled for the Friday that week. Friday morning/last minute, interviewer cancelled. Rescheduled for the following Tuesday. Asked questions and studied for interview before and in between. Tuesday morning/last minute (again), recruiting cancelled the interview (again). Was told the CEO did not advance me and an error had been made by recruiting. CEO could have indicated a lack of fit during the initial call rather than suggesting the decision was gated on engineering approval. Recruiting had multiple touch points and a week to catch this. Apology was ungracious and was not signed off/closed by any person, just a blank line. I hope this is not an experience future candidates receive.
