Not enough experience to say "typically", but things of my top of head:

1. Credentialism or "too narrow thinking" in hiring: we use AWS so your GCP experience does not count. That candidate is from Columbia so we should give this candidate a chance while the person from Rutgers gets passed on.

2. Not recognizing the importance of holistic system design. In backend or distributed systems you often need good design. It can often be good to stop the world for a week to fix the design.

3. Lacking a general sense of humility or having too much ego. Most people are not Alan Kay, nor are most leaders. As a leader, embrace some fallibility and limitations of being human.
