I had one of the worst interview experiences of my career with Costco GCC. After 5 rounds of interviews, all marked successful, I received a selection confirmation email and was asked to submit documents . Shockingly, after document collection, Costco GCC backed out without explanation. This is not just unprofessional — it shows zero integrity, zero accountability, and zero respect for candidates’ time and effort. An organization that cannot honor its own written confirmation clearly has no values and no hiring discipline. If this is how they treat candidates before joining, imagine the instability after joining. Choose this place only if you are comfortable being dropped anytime without accountability. Broken process. Broken trust. No ethics. Avoid if you value professionalism and job security.

First: screening round with the recruiter; Second: Technical round Third: there may be another technical interview but usually it is the Managerial round. Fourth: There may be a round with someone from the leadership. It is a pleasant experience overall as all the interviewers were quite friendly.
