It was a good one, All rounds completed in one day and they released offer after 1 week. No negotiation on the numbers. After joining, client interviews were there so be prepared for that as well.

Technical Interview Focus on your core technical skills (depends on your resume). For Mainframe roles → COBOL, JCL, DB2, VSAM, IMS, CICS, utilities, debugging. there were questions on my past projects, problem-solving, and live coding. For me Managerial Round merged with Technical Focus on: Problem-solving in real scenarios (e.g., missed production issue, performance tuning, client escalations). Team handling / leadership skills if you are senior. Behavioral questions: handling pressure, deadlines, conflicts in a team. Client interaction ability. HR Round: Usually the final step. Covers: Salary discussion (hike from current CTC, TCS bands). Work location (TCS has strict location policies). Work culture & shift flexibility (support projects may require night shifts). Offer & Background Check If you clear all rounds, TCS releases the offer letter. Background verification (employment history, education, etc.) is mandatory before onboarding.
