Supposedly Circle is getting so many qualified applicants that they have currently moved to requiring you to take a 90 minute CodeSignal test/evaluation with a few levels of difficulty that wasn't all that hard.

The hard part is, for some people such as myself with 10+ years of experience, is coding under pressure. The example problems that the recruiter sent out were nothing like the actual test, and I wasn't familiar with how to submit each level for evaluation, nor was I even sure if I was following their directions correctly. If you're like me and don't like being gate kept by extremely contrived coding exercises that give absolutely no bearing on my day-to-day performance, this is yet another company to avoid. Other than that, the recruiter responded fast, was courteous, and I had no issues with dealing with the personnel.
