I've been working with software development for nearly 3 years, but always in small companies with 6 employees at most. In Dec 2018, I started working in a big company, and I'm still feeling completely lost.
When I started, no one told me who my manager was or what project I'll be working on. I started with configuring my computer before asking who my manager was, what I'll do etc.
When my manager finally showed up, he told me that I won't work on external projects for now, but when this happens here, they ask the employees to work on an internal project. I finished all my tasks in about 2 days, which was 1 week ago, and since then I, again, don't have any work to do.
I sent a message to my manager this morning to ask for more work including suggesting new things, but I think he's on vacation.
I don't know whether what I'm doing in the meantime is correct e.g. studying. It's really annoying to me to just sit here and be useless.
What do you all recommend that I do with my time?
EDIT
I was studying yesterday, and I found something that I would like to implement in this internal project that I was working on before. Thus, I think this could be productive for me today. My plan is, when I finish this, to send an email to my manager's boss, who interviewed me, and ask about what's happening and what the plans for me are.
EDIT 2
I sent the email to my manager's boss, and I tried to be diplomatic in saying that I am not trying to go over anyone's head, but my manager is on vacation this week and I don't have anything to do. I think he'll answer tomorrow (I hope) because it's almost 6 PM.
EDIT 3
My manager's boss called me today to chat about my email that I sent yesterday. On my email I told about another skills who could be useful for the company, and I could help when I'm without any task and my desire to learn new technologies too. He will give me a MacBook to help in another project with iOS development. I'm an Android developer with some XP in iOS.
He have told me about that internal project, my manager didnt give me permission to see the tasks so he gave me now and I will implement the new features. He was very understanding about my email, and the fact that I'm about to be able to work with another technology too makes me feel happy.

Wow. It's been more than a year since I made this question. Time is going fast. Well, all can I say is I joined in this company at the "wrong" time. A lot of changes were going on that month. Three months later, I was sent to travel to work in a very big project. I did well on it. Now, I am earning 75% more than I was when I started in the company. It's been a pleasure to be here tbh. Time is the answer; I was ready to give up in the first month. Thank you guys.

Man, I'm feeling old right now. It's almost 5 years since I've become an employee here. When I made this post I was afraid about my skills and how I could fit in this company. Now I am one of the main skilled employees here, that's why I am now the Head in my technology.
Wow! So many feelings right now. I remember exactly how I felt about this day when I made this post. I was lost because I didn't know if I was in the right profession because I had no money. Now I'm earning 5 times more than I was, I have a brand new car (really difficult to have here in Brazil), and I can help my family every time they need to. This is insane! Thanks again. I hope to come back here in few years telling you guys how good is my job :) (Oh and I think my English is getting better)
