I'm a tech lead for a couple of years at several companies and highly appreciated. I also had a prior conversation with the R&D manager who told me how he thinks im a great fit.

I had 2 technical interviews with senior engineers.

They seem to have the same question being asked, but I wasn't aware of that so I didn't come "prepared" with how to answer it (I guess some do and it's doesnt make the process fair IMO)

I felt I communicated well enough and they even told me in the interview that it was good.

Later I got rejected and when I asked for feedback, they told me they expected me to lead better and that my thinking was not fast enough.

Eventually I was under the impression they had some sort of a checklist of how a tech lead should act like, with the company's "DNA" and that's really a shame, because not all tech leads are super energetic and "fast thinkers" and you need to have some diversity.
