Infosys interview questions
InfyTQ or the HackWithInfy route. Expect a strong pull towards DBMS and SQL, and a puzzle in the technical round more often than at other service companies.
The process
- Online assessment — aptitude, pseudocode, puzzles
- Technical interview — DBMS, SQL, one programming language, project
- HR round — flexibility, motivation, communication
DBMS and SQL
What are ACID properties? Give an example of each one failing.
Difference between DELETE, TRUNCATE and DROP.
Write a query using GROUP BY with HAVING.
What is an index, and when does adding one hurt?
Explain joins using a real table you have worked with.
Programming and logic
Reverse a string without using a built-in function.
Find duplicates in an array in a single pass.
Explain recursion using a problem you have actually solved.
What is the output of this pseudocode, and why?
Explain pass by value versus pass by reference.
HR and behavioural
Why did you choose your engineering branch?
Describe a time you disagreed with a teammate.
What do you know about Infosys beyond the services list?
How do you keep learning outside coursework?
How to practise these
Read a question aloud with Answer Round AI listening on your microphone, and answer it as if the round were live. You get a transcript of what you actually said, a draft built from your own resume to compare against, and a saved session to read back. Work through one group a day rather than skimming all 14 in an evening.
These are question patterns, gathered from publicly shared candidate experiences and Infosys Limited's published hiring process — not leaked question papers. Use them as practice material, and check the rules of any live round before using assistance in it.
