It had basically 4 rounds and hr. but I went till 3rd round. 1. They will give an assignment to build using any framework like react or plane Javascript. Ex: shopping cart, searching like YouTube 2. Pair programming - where in you will be asked to implement an extra feature for the same code written in first round. Go through all the hooks and fetaures of react. 3. System design round. Lld and hld for any typical known system.. Twitter, what Sapp, bookmyshow. I dint do well in 3rd round so there the story ends.

They only need TDD , if u know that acc to what they do then only it's good. No need to know anything else for react they only need tdd using jest , if u used cypress or something u know they will be like it 's now tdd for take home round generally it should be one assignment but they gave me 2 and passed if it was not tdd as u said then why take interview
