I'd say it could be better to transition from InMobi to a company between it and FAANGs in brand value.
Something like Flipkart, Walmart, PhonePe. They're bigger brands than InMobi and would be a good addition to your CV. You can then transition to FAANG roles.
I see the following cons with this move?:
- You'll miss out on benefits like stock, good internal opportunities, good insurance etc.
- If you become a contractor there's some risk in you being seen as a contractor even for your next transition imo.
- It's super easy for them to lay you off and chances of a layoff are high too.
