Razorpay Software Development Engineer In Test interview questions

I had a coding round where interviewer shared a common notepad. Guys, you can atleast use coderpad. I was asked to implement a stack class and then interviewer kept on asking me to update it, like return response in json, handle server failure cases etc. Guys, every automation framework is different and you should not look for exact implementation as your company have. Judge on person's ability to understand a new company framework and mould his coding skills accordingly. I have good automation skills but still wondering that how could you judge on basis of 1 problem. I also shared my website written in python-flask to reconsider his judgement on my coding skills, but he was least interested. I have had great experience in payment gateway industry, but that also did not matter. We always gave better consideration for someone having payment gateway experience since it takes 6-8 months for new joiner to understand the domain, but seemed this was irrelevant for razorpay.
