L64 Offer - Where did I go wrong here

- Spoke to recruiter to confirm Microsoft L64 position - When asked about salary expectations, noted $190-$200K + other bonuses and incentives (tried not to give specifics) - Recruiter mentioned ok, knows AMZN pays higher but may be do-able since location is NYC. - Got the offer: $150K base / $50K Stock vest 4 years / no sign on / RBI and CBI total 20% of salary - I mentioned this is a pay cut for me and I cannot accept this - Recruiter said I mentioned $150-$160K base on our initial call. I disagreed and reminded recruiter I wrote this in an email - Recruiter asked what I was looking for and I mentioned $200K base / $400K stock / $100K sign on (realize this is a bit high but figured this gives them room to negotiate down) - Was told these numbers are for L65 or L66 positions, not L64 but will ask HM - Got the call back and was told can't meet this offer and will let me know if there are any other roles in the future. Said the team had no budget for a sign on bonus and next time I should specifically mention what I want upfront. Offer rescinded, no further negotiation. This is my first time in a while really negotiating (20 YOE total in the industry). So not sure what went wrong here. I thought by telling them upfront a base range this gave them an idea if I should even be considered for the loop. Also just the # of years I have worked. Team and role seemed like a great opportunity and I was excited. But now super disappointed how this did not work out at all. Wasted tons for time preparing for the loop. Would like to learn from this experience to understand what I should do differently next time.
