They will first give you a home assignment which won't make sense as the expectation is way too high and the solution won't be discussed in the further round. After that, there is a live call where they just share a code sample and ask to find a bug in a very limited time which won't be possible as the code itself is way too long. Post this they just ask advanced JS terminologies. The call will take more than 1.5 hr and they dont care what you type or say.
