For a new job is a common problem. When I was younger I always thought I must be stupid because basic setup, builds are done well and I just can't figure it out. Now I realize that most teams have random quality builds and likely there is some peculiarity that you can't google for. You need a buddy to keep asking, also pair programming is great, if you can sit with someone else and watch what they do it really helps.
