In round 5 the task was quite frontend specific so experience with javascript and javascript libraries would have granted a huge advantage (while being unexperienced in that meant a huge drawback). The task was not complex, it didn't require any particular algorithmic thinking. Diverse preference of the hourly changing "observer" colleagues on how the task should be solved was a bit confusing. Most of them were helpful, although there were some with a quite negative attitude. Since we discussed in round 2 that I hadn't have much experience on frontend and JS, I believe they should have warned me at least before round 5 to look through JS as almost no other knowledge was required to finish the task in time.
