I applied through a recruiter. The process took 2 weeks. I interviewed at Groupon (Austin, TX) in Oct 2018
Interview
A recruiter reached out to me on Piazza and scheduled a phone interview. Then I had 2 rounds of final interviewer at GHC. Although the questions are mainly about the coding problems, I was asked about my previous internship experience in details. So definitely prepare to talk about things on your resume.
