Good evening, I got some uncertainties and need some advise or any experiences 'story' from you guys. The question is quite straight forward but I gonna clarify somethings in details.

My Background

I just graduated from my university 6 months ago. Being offer from 4 companies after I go through some interviews. Now I'm working on a banking services company, everything is consider 'ok' except I had a genius team lead which does not share enough information to let me do a task/work.

Situation faced

In my team, there is a "ask to know" culture. When you are going to guess or try some methods to solve the problems, I need to ask to make sure I do not do something stupid and when I asked my team lead...There're only 2 situations,

1st: I being given a strange look like: "do you know what are you do/said just now? Just follow the standards, I do not care!" (Felt humiliated)

2nd: Get the answer but my team lead suddenly in bad moods, I think thats I have waste her time for some simple questions which I do not know.

Add-Ons

My team lead is really a clever and a smart senior developers/programmers, sometimes she will brief through the tasks while sometimes not. Depend on her moods. There certain times I am look-down on myself and felt want to quit/resign. I'm still under-probation and had joined this company for around 4 months. I felt like I do not have the innovation skills which I used to had in university and lose my self-confidence when communicate to others.
