1 stage: task to implement simple end2end service - spring boot, rest API, JPA + test with limited time - 3h.
2 stage: review your solution from stage 1. and Pair Programing - quite easy to resolve.
Generally, it was time-wasting - stage 1 and stage 2.
For stage 1 - a review was not made, and a general question about the feelings?
Pair Programing was indeed a technical review, the person who made a PR was totally introverted, and any asked question finished with an answer - do as u want.
