Quora, Inc. Software Engineer(Internship) interview questions

Applied through referral. Interviewed at Quora. Resume screening -> CodeSignal -> Virtual technical interview via Zoom and CodeSignal Playground. Great experience. The recruiter and interviewer are friendly and efficient in communication.

Got CodeSignal invitation the day immediately after I submit application from their website. CodeSignal is not a great way of measuring score. I completed 3.5/4 questions within 40 minutes, and then I was stuck on the time limit of the last one until the end. Still, my score is very low although I almost finish all the questions within a short time limit. Confused by how the score is calculated.
