Applied online and received an online assessment (OA) after 1 day. I had two weeks to complete it. It was CodeSignal's proctored GCF, with 4 questions for 70 or 75 minutes. All questions were array-based; nothing fancy like trees, DP, or anything like that. I did not hear back after the test.

A sample test is available, although only after you click to take the test (which then asks if you want the sample test or to go forward). There is also one sample test link in some of their help pages.

I suggest taking their practice questions; you get 2 every day, and these will definitely help.

Solve:

• 2 easy array- or string-based questions
• 1 medium matrix problem
• 1 medium / lower hard array problem
