Interview Preparation Tips

Interview preparation tips for other job seekers - If a candidate is investing days from his personal time in interview process and reaching the final HR round atleast have the decency of telling the reason for not moving forward. They didn't give any reason for not selecting. And when when I tried to contact the HR she just ignored calls and ghosted. Even in the behavioral round of interview they asked weird questions like what is your CET rank, what is current salary. For a experienced candidate having 3+ years of experience and clearing technical rounds how does CET rank matter? And I had clearly mentioned the salary expectations prior to the interview process. Please mention CET rank as a criteria in job discription to avoid such situations and let your interviewees know of the salary expectations to avoid salary discussions on a behavioral round. When trying to contact the HR to ask reasons for not moving ahead they just ghost you. No wonder Rolls-Royce has a glassdoor rating of below 3. Didnt expect such bahavior from an OEM.
