Tips for Success at Infosys

  • Register on InfyTQ and complete the course curriculum; finishing 80%+ of courses sometimes grants a direct interview invite, bypassing the aptitude test.

  • The DSE and Power Programmer tracks are significantly more competitive — target these if you have strong coding skills and want higher starting pay.

  • Practice SQL extensively, not just coding: Infosys tests database knowledge (joins, window functions, query optimization) in technical rounds.

  • Infosys’s 1-year service agreement for freshers in India requires repaying ₹50,000 in training costs if broken early — factor this into your decision.

  • Learn Infosys’s key platforms: Cobalt (cloud), Topaz (AI/ML), and Wingspan (learning) to demonstrate business context.

  • Behavioral interviews follow STAR format strictly; prepare 4–5 stories covering collaboration, technical challenge, leadership, and failure/recovery.
