Maybe I should be more clear - I didn't go to a Tier1 public school, didn't get into an elite school, how screwed am I?
Once you've done something in the industry, almost no one is going to give a hoot about what school you went to, they're going to care about what you've done in the industry, but at the start at least, you may have to settle for something a little shittier.
I did ok in college and very well in the private sector. I started as a sysadmin for a small finance company and am now a senior software engineer at Amazon Alexa working on ML for search. Hard work always pays off as long as your in the right field ( comp-sci is a great field ).
