Tata Consultancy Services Data Analyst interview questions

I applied through the company’s website for a Data Analyst position and have two interview rounds scheduled: one technical to assess my skills and one HR to evaluate cultural fit and personality.

The interview process at Tata Consultancy Services (TCS) for a Data Analyst role generally includes the following stages: 1. **Online Aptitude Test (if applicable):** Assesses logical reasoning, quantitative ability, and basic programming skills. 2. **Technical Interview:** Focuses on your data analysis skills, experience with tools like Python, SQL, and big data technologies, data visualization, and ETL processes. Scenario-based questions are common. 3. **Managerial Interview:** Evaluates problem-solving abilities, past experience, teamwork, and alignment with TCS values. 4. **HR Interview:** Assesses cultural fit, communication skills, and discusses salary and other formalities. 5. **Offer and Background Verification:** If successful, you receive an offer, followed by a background check. Preparation should focus on core technical skills, understanding TCS's business, and practicing interview scenarios.
