A headhunter reached out. Light and informal interviews. They made an offer. Typically, they include stock options but did not do so for this role. Managed to negotiate for options (which other recruits were receiving left and right) which went reasonably well. Suddenly, after I had handed in my notice at my previous employer, they took back the job offer with no explanation. This was purely based on asking additional questions about the employment contract (the recruiter confirmed they had finalized all evaluation at that point). The communication was polite and constructive throughout the process. But suddenly because of asking additional information about some of the points in the contract in a good-natured way, they pulled out in a way which left me without my previous or new position. I urge you to be very very careful and make sure you are not let down in a similar manner.
