Frontend Engineer interview at ImagineArt / Vyro.

I have about 6 years of experience in frontend development living in Islamabad. Got an email from Imagine Art / Vyro for the frontend engineer interview. In the email they say that in this initial interview we will have discussion about JavaScript core concepts, reactjs, nextjs, typescript and micro frontend Architecture. And it won't be a white board deep whiteboard session.

What sort of interview questions should I expect and prepeare for? What the next step would be in the process? Will there be any LeetCode type questions? If anyone here have gone through their interview process please guide.

And what sort of salary should I demand for my experience.

Any sort of help would be greatful.
