ThousandEyes Software Engineer interview questions

Applied through university portal and was contacted by a recruiter. Went through a brief 30-minute phone screen about my technical and career background. Was then sent a questionnaire and coding challenge, was not contacted again after.

Got a message on LinkedIn from the company recruiter. I showed interest and the recruiter sent my resume to the hiring manager, who was wanted to continue the interview process with me. I got a take home coding project-- if it was reviewed favorably by ThousandEyes, they were gonna call me for an onsite interview. Since I had an offer pending, they expedited the reviewing the project and got back to me. The recruiter told me that they didn't review my project favorably and didn't wish to go on. I spent a good amount of hours on that project and wanted some sort of feedback on it. I didn't get any. I have turned in multiple coding assignments of the type at various companies, and I have always had positive feedback. Given the time investment for this project, I wanted some feedback so I at least get something out of it. I believe if a company is going to require 8 hours of your time for a project, some feedback should be courtesy.
