My guess would be yes, it's cultural. I'm not Indian but spent about 5 months there. Overall my impression was that people act much more on direct feedback.

It would be typical to do the first thing that comes to mind, then see what happens. No negative feedback? Done, move on. Negative feedback? Try the next best thing that makes the negative feed back go away.

People will not wonder whether they might bother you. Just start talking. Maybe try to sell you something. That's often annoying. But also just be curious, or offer tea. You react annoyed and tell them to go away? They most likely will and not think anything bad of it. You engage them? They will continue. Most likely won't take "hints" or whatever subtle non-verbal communication a Westerner uses.

I found it quite exhausting in the beginning, it feels like constantly having to defend myself when I want to be left alone. But after I started understanding this mode and becoming more firm in my boundaries, I started to find it quite nice for everyday interactions. Much less guessing involved, just be direct.

Professionally I haven't worked much with Indians, but my expectation would be that it's necessary to be more active in ensuring that things are in track. Ask them to reflect back to you what the stated goal is. Ask them for what you think are obvious implications from the stated goal to ensure they're not just repeating the words. Check work in progress more often.
