Not a good experience. They give you a link to a live coding challenge. You have 3 or 4 tasks. It is a combination of easy-med-real? examples. When you finish something in good time or even better in a very short time, they want you to rewrite it in a different way, much harder or so. In my case they wanted me to write some standard library class from scratch out of my head. The rest of the tasks are IMHO from leetcode. The one that is "near" the real use case scenario of the work you will do there is without a fantasy. I asked them about the testing (no tests as I read it here): But no answer
Deployment to Prod (Ad-Hoc): yes sometimes.
