I get that this is a nice problem to have so here it goes:
Company A - start-up, £65k + 15% bonus it's technically remote, but have made noise about it being hybrid (which I can't commit to, and they now it). Contract signed.
Company B - Big Tech, salary unknown as they changed the role half way through, and up to today I have no clue what this final role is. I've queried and so far I've had crickets. Fully remote. Previous role I was interviewing for was £80k + bonus
Company C - Big Tech, £62-£82k (base) + 20% bonus. I assume I would get at the very least £70k based on experience. Fully remote.
Company B apparently liked me so much that they fast tracked me to a final stage next week.
Company C is hiring for a niche role (which is how I got the interview with Company B), so I think my chances are high.
