Don't quit! I SUCK at those algorithm tests but frankly the best engineers that I've hired have not done a great job at them.

Instead communication skills and a willingness to learn have been much bigger indicators. There are plenty of startups that will LOVE to have you. Focus on getting a job at earlier stage startups. Create your own projects as well. People like seeing those projects to show that you're passionate about coding.
