ServiceNow rounds in detail

ServiceNow hires through a conventional but thorough enterprise loop: recruiter screen, a HackerRank-style assessment for many India requisitions, then panel-style technical rounds mixing DSA with JavaScript/Java platform questions, a hiring-manager round and HR. Its Hyderabad and Bengaluru development centers are among its largest sites, so the India process is mature and well-calibrated rather than an outpost afterthought.
