I applied to Tinder online and was contacted by a recruiter for a quick chat a few weeks later. She didn't update me for a long time with the next steps, so I emailed her back and was notified that she no longer worked at Tinder. Another recruiter set me up with a technical in which two people interviewed me at once. The question itself wasn't difficult, but I probably got rejected due to taking too long to implement and being scared to properly debug in front of both interviewers.
