Background: Unlike most tech companies that recruit candidates for specific teams, new employees at Meta need to join a bootcamp program. While finishing up many online trainings, random technical coding tasks, and setting up firmwide logistics, new employees are required to look out for new job openings from the company’s Jobs Tool similar to Linkedin’s jobs panel . Ideally, a new employee should find a team to join within 6 to 8 weeks to graduate from bootcamp.

4 outcomes of cash secured puts: Option expires OTM: Keep the premium. Collateral is freed to use. Option gets assigned ITM: Keep the premium. Collateral is used to purchase the underlying stock shares at strike price. You are okay or intented to own the underlying stock, hoping that it will rebounce above the strike price. Rollover: Buy-to-close on an option that’s already ITM, and sell an option that’s in the future, OTM.

Delta: \(\Delta\) measures the sensitivity of an option price change in relation to the changes in the underlying stock price. $$ \Delta = \frac{\partial V}{\partial S} $$ , where \(V\) is the option price, and \(S\) is the underlying stock price. Call Delta range: \([0, 1]\). Put Delta range: \([-1, 0]\). The closer Delta is to +1 or -1, the more strongly that the option's premium responds to the change in the stock price.
