I got insta rejected in interview when i said this in response to interview panels question about 'thoughts about golang' .
Like they said, 'interview is over' and showed me the (virtual) door. I was stunned lol. This was during peak golang mania . Not sure what happened to rancherlabs .
It’s part trying to keep a common direction and part fear that dislike of their tech risks the hire not staying for long.
I don’t agree with this approach, don’t get me wrong, but I’ve seen it done and it might explain your experience.
