26,577 technical test lead interview questions shared by candidates

he interview process will consist of three rounds: Round 1 – Problem Solving and Automation Fundamentals This round will primarily focus on Data Structures and Algorithms (with coding problems at a LeetCode medium level of difficulty). Along with that, there will be questions around automation frameworks and Selenium, covering both conceptual understanding and practical implementation aspects. Round 2 – API, Database, and Advanced Testing Concepts In the second stage, you can expect a mix of problem-solving questions (again, LeetCode medium level) along with in-depth discussions on API testing methodologies. Topics will likely include database concepts, querying, and validation, as well as practical API testing using tools such as Postman. This round is designed to evaluate both your coding ability and your applied knowledge in backend/API validation. Round 3 – Founder/Leadership Discussion The final round will be with the founder and will lean more toward open-ended, real-world problem scenarios. The focus here will be on how you approach practical challenges, structure solutions, and apply your technical expertise to business-driven problems. It is less about pure coding and more about analytical thinking, problem decomposition, and solution design.

bold first round 1. anagram 2. factorial 3. check if string contains all a to z characters ( you can use hashset and check size if it is 26 then all char is present in string) 4. if there is any vowel in string, just replace it with $ 5. left join query write ( 2 table employee and project) 6. insert query write 7. cake cut 8 pieces puzzle 8. api response - related to json array and their modification ( their is a json array if any value present in that array has size >4 then truncate it to length 4 only ) -- example if "abxbndhhdjd" is a value then make it to "abxb" 9. jenkins basic use - pipeline basics 10. 2 sharks eats 2 fish in 2 days then 10 sharks eats 10 fish in how many days ? Bold second round- 1.8L 5L 3L puzzle 2. List -- ["ABC","MNO","XYZ"] o/p - ["ZYX","ONM","CBA"] 3. same api needs to be executed for 3 countries(how would u optimise suite run time) 4. issue comes in production , how will u debug 5. Salary and employee table -- find avg salary where department is IT 6. API push data in queue and queue pushes data in db ( queue can take 30 mins) how would u automate it 7. there is json array in response, pick any item and how to do assertion with db 8. Service A calling Service B ..Service A is down , would it impact Service B and how would test now ?
