Unity interview questions

Had a first round interview with HR which was a typical first round interview. Was told that the HR Manager would forward my resumé and application to a hiring manager and if he likeds my profile, they would invite me for another interview. If not, the HR Manager promised to get back to me with feedback on the reason not. Never heard back. Yet, Unity has the audacity to ask me to a "Candidate Survey" in order to improve the "Candidate Experience" at Unity. Could have been more professional.
