Regular HR interview, the role, salary expectations, visa requirements. Why am I interested in this position? Tell me why do you want to work for us? How many years of experience?

It first started with a phone interview with HR, then they brought me in the following week to meet with a HR director, the hiring manager and the VP of the department. Questions were easy, smooth process and constant reinforcement that I was a solid candidate, at least for a 2nd interview. So after 4 months had passed and constant emails with HR saying the process is delayed, they found a candidate with no feedback. Terrible communication, poor management of interview process.
