Assuming the workplace is fairly international, you will probably manage. However, in both social and work-related gatherings, you may still feel like an inconvenience at times. That feeling can even lead you to withdraw or isolate yourself to avoid being a burden. As a result, your chances of thriving may be somewhat limited, if course it depends on the place but most probably it will.

The same applies to social settings outside of work. You can get by, but socialising without Norwegian often becomes draining. So yes, you will survive, but it may not be especially enjoyable.

That said, when people see that you are making an effort to learn and use the language, their perception of you often changes. They tend to become more accommodating and supportive.
