Docusign Software Engineer interview questions

I applied online, got a recruiter call then went on with phone and multiple 1-1 rounds. Algorithms and Data Structures, white boarding and general questions. Make sure you are prepared to deep dive on your background.

I applied and got an automated email with specs for a project for me to complete and send back to them. I did and emailed it back to them and did not get notice of receipt. I emailed them back 2 days later to ask for a receipt confirmation and got a confirmation two days after sending the email. Then 3 weeks went by, I didn't hear back from anyone. I emailed to ask for feedback and no one responded. 5 weeks later, I got an email saying they are not going to move forward with my application because I did not use OOP (I did) or Separation of Concerns (I did).. Oh well..
