Hi! I really needed some advice!

I've been living abroad for 1.5 years, and I've been learning the local language since (from lvl zero). I was able to reach B2, and then started jobsearch - I was realistic, so not in my original field (engineering).

Interviews went well because I could easily prepare in advance, and I even refused an offer, because after I learnt about the details I knew my language skills wouldn't suffice.

In the end, I took a job at a small company 2 weeks ago. They hired me for simple, unskilled work, but the job is much more complex and there's also a high requirement of precisity.

At least half of it, if I understand what I'm being told. Not to mention the speaking part. I often need to contact other departments, too.

So what I wanted to ask was: is it like this for everyone at the beginning? Or is my language proficiency really not good enough to do this job? Or should I wait a little longer and ask for feedback?

Thx.
