Just had coding interview but I feel like I bombed. Feels bad man.
The one I "bombed" is the one I got hired for. A lot of times, people are looking to see how you think and approach a problem. This could be the case for you this time as well. You already did your best so try not to cause yourself anguish by mentally harping on how it went. If there is something you didn't understand or know for a fact that you missed, research and learn about it.
