Persistent Systems Cloud Engineer interview questions

My referral went through a Nightmare - gave 2 round's of technical interviews in Cloud team. Had to continuously follow up for feedback - had to join another company - recruiter doesn't pick the phone-finally in person was scheduled with a lady called Rupa Solanki . Looks like she enjoys making mokery of candidates and humiliating them interviews-not only was she rude but also arrogant. My referral literary wanted to leave the premises and was in tears later. Never will I refer candidates and recruitment team shud stop begging referral's if this is the way candidates are treated by panel's and TA member's
