A well-known recruiter reached out to me via LinkedIn. I wrote them back the same day and waited a week, but they never wrote back. Even with a couple of follow-ups, they still never got back to me. I ended up getting an interview a year later. With the way they interview, saying if I don't know a certain abbreviation, which I never encountered before, then we can't hire you, I can see why positions still remain available. From what I read on Glassdoor about the data department, it does not surprise me that they wrote a 1-star review.
