ServiceNow interview questions

HR contacted me over linkedin. After a couple of phone interactions HR asked me to be available for half a day, with just 1 days prior notice.Was not flexible to postpone. I was present at the scheduled time. They made me wait for 45 mins. And finally interviewer arrived. Interview went for around 1 hour and the asked me to wait further. They made me wait for 45 mins and when I contacted the HR he is clueless and asked me to leave for the day. HR never got back, though he he said to do so. If there is such an unprofessional treatment for an interview candidate, I wonder how they treat the employees.

Two rounds of telephonic round. third round in hyd office. face to face interview lasting around 1 hour. focus on what i have done. try to showcase jd match with your experience
