People are getting multiple offers in a market like today, and they are not showing up on their first day of work
-- Kathryn Vasel, CNN Business
We (Silicon Valley firm) have not had anyone accept an offer, and then not show-up for work! We have had people ghost us after receiving the offer letter (heh) and several verbally accept the offer, and then ghost us. I don't know about the rest of the country, but Silicon Valley has always been a bit quirky due to the competition for engineers.
