I did. Once I joined the companies that did not openly answer my questions during interviews (about finances, strike price, etc.), I ended up realizing all the negatives/problems of the companies from the inside.

Then on, I had only two choices: (1) ignore the problems and not worry about future, or (2) act fast and start interviewing until I have options if something goes wrong. I chose the second option, and hence a lot of interviewing.
