Help with interview resources + preparation guidelines

Swiggy has become a toxic Ex for me now and there is no time to think about it at this point (for me atleast) I need to get back on my feet soon (sole earner in my family) and need some help.

It has been a really long time since I prepared and stepped out there, so need some help in knowing what's going on out there. It would be great if someone can help with these:

1. Any interview resources I can start with
2. What all things I need/should prepare for
3. Any tips and tricks for the interview preparation

I think it will be a lot of help for me and others too who are in the same boat. I was an SDE2 here and thinking of stepping up to SDE3 as well but right now even an SDE2 role would suffice. So will prepare accordingly
