HR approached me on the same days after their Co founder added me on Linkedin. Had a positive experience with the HR although they did not have an official JD or job opening listed on their site.
Although the interviewer was polite, my interview delved too much into what I wanted to be in my next role and not what their expectations are. For the first 25 minutes it was more general stuff like how do I manage projects, my favourite projects, workflows, etc.
When I asked what would be the qualitative and quantitative success metrics for the role, I got a super vague response and felt like I wasted my time.
