Should I be investing time in learning the local language at work?

I’m working at a FAANG company in the Tel Aviv office, and one thing I’ve been struggling with is the language situation. Everything official, docs, group messages, tasks, emails, is in English. But most of the casual conversations and a lot of the meetings (especially the side convos during meetings) are in Hebrew.

I actually do speak some Hebrew, I’m like a 6/10, but it’s still really hard for me to follow deeper technical or high-level discussions. It just takes a much stronger grasp of the language than I currently have. People are super nice and switch to English when I’m involved, but it still makes me feel kind of disconnected and behind.

Now I’m torn: should I seriously invest time into improving my Hebrew, or just focus fully on ramping up technically and learning the codebase? I’ve seen other people here who only speak English and seem to be doing fine, even at senior levels, but I also wonder if not speaking Hebrew fluently is going to make it harder for me to grow, get promoted, or even just be included in more nuanced discussions.
