Recently admitted to TUHH M.Sc. Computer Science – I have a few questions about studying and living in Hamburg

I recently was admitted to TUHH for a master's in computer science winter intake. I would like to ask a few questions about the uni and the city.

1. How difficult is it to find a student job related to computer science?
2. Does knowing German make a big difference when searching for a job, or are English-speaking positions available?
3. Is the city expensive? Also, for accommodation, can I find a place easily?
4. Is the program very difficult, or is it manageable with consistent effort?
5. Do students usually finish within two years?

I'd really appreciate any advice or personal experiences. Thanks in advance!
