Ask HN: Is this Paypal experience customary?

Here is a succinct timeline of the events.

  • I received a Paypal notification that 600 USD were deposited on my account.
  • I was not expecting any money, so I logged in to see what this is about.
  • Apparently someone paid me for an item they bought on Ebay.
  • The information contained on my Paypal account about the transaction, did NOT contain any information on what this is about.
  • I am NOT an Ebay seller, so I have nothing else to follow this up.
  • My first thought (apart from quickly spending the money) was that some poor soul after thinking that they have paid for an item they would wait for ever for an item they thought they purchased, only to never receive it.
  • So I spent some considerable amount of time trying to locate the seller from their name only (did not have an email) by googling around, to clarify the issue
  • As it was getting late, I left the issue to continue the next day.

What I Wish I'd Known About Equity Before Joining A Unicorn

What I Wish I'd Known About Equity Before Joining A Unicorn

Disclaimer: This piece is written anonymously. The names of a few particular companies are mentioned, but as common examples only.

This is a short write-up on things that I wish I'd known and considered before joining a private company (aka startup, aka unicorn in some cases). I'm not trying to make the case that you should never join a private company, but the power imbalance between founder and employee is extreme, and that potential candidates would
