Esri Software Engineering interview questions

Had a very bad experience ever while interviewing for ESRI. Initially when my first round interview was setup, the interviewer was really kind and finally we managed to have a interview session. My feedback was great for the interview and was assured a second round interview. Weeks after weeks I kept emailing them, I was assured a second round interview in all the HR replies. Finally when I asked them again, I received a generic rejection email.
