Pergunta de entrevista da empresa Swiggy

Round 1 – Coding This round was fair and good. The interviewer asked standard coding and problem-solving questions: Balanced Parenthesis problem. Find the second largest element in an array. Discussion on time complexity and space complexity of solutions. How to improve time and space complexity. 👉 Overall, this was a smooth experience, and I felt it was a fair evaluation of coding skills. Round 2 – Automation Framework Design & Challenges (Worst Experience) This was supposed to be an Automation + Framework design round, but it turned into a system design + DevOps/tool-based grilling session. Problems I faced: Interviewer joined 25 minutes late. Instead of 2–3 hrs, it dragged to 3 hrs 25 mins, overlapping with my manager meeting at current job. I had to call the HR 30+ times to get it rescheduled, and only when I dialed a different number did she pick up. Questions asked: What do you mean by Redis? What is Docker? Write Docker code. If I am a student, how would you explain Docker to me? What is Kafka? Login API case: username + password with 1 lakh characters → what should be the response code? (I said 400, but they expected 401.) What is p90, p95 in performance testing? Steps to implement. Apart from p90/p95, what about p50, p75, etc.? What is JMeter? Write automation code: login to Facebook → go to messages → open latest message of a friend → type and send. What is sequential data vs non-sequential data? Which is faster? 5 classes running in parallel → add one more class → how to ensure no impact on speed. What is asynchronous? How do you ensure your code is correct (even mentioned ChatGPT)? What are the types of performance testing and the tools? If I said “I don’t know”, the interviewer responded rudely with: “You need to know everything. See me, in 4 years I became a Team Lead.” (Honestly, I don’t know how he became TL with that attitude, given he didn’t respect time commitments.) What tests can we do in JMeter? If 2 laptops send same request in Postman and one gets faster response → why? (Answer: cache. But question was poorly asked.) My Feedback The first round was good and relevant. The second round was the worst experience of my career: unprofessional interviewer (late, dragged too long, unclear questions, rude attitude). Instead of focusing on automation framework and challenges (as promised), they asked random DevOps + performance testing questions. Poor HR coordination → had to follow up excessively for rescheduling. 👉 Overall, very disappointing experience in Round 2.
