Entrevista
Applied on Linkedin. Contacted by recruiter within the same week. Everything went fine and recruiter asked availability for next round of interviews. Never heard back thereafter. Didn't expect to be ghosted after asking for availability. A simple rejection would have sufficed instead of keeping the candidate in the dark or getting hopes high by asking availability for next round.

After applying, I had a behavioural phone screen with a recruiter, followed by a technical phone screen with a data scientist (who seemed to be doing interviews exclusively now). I was told the next steps were a phone call with business stakeholders, followed by an on-site interview day.
