Tech Mahindra Python API Developer interview questions

Started with basic introduction about myself. There were just python and fastAPI coding questions asked. 3 for python, 1 for fastAPI. I was able to code out and give correct output for all of them. Despite this, I wasn't selected. They didn't even had the courtesy to give me an update about the same. I had to contact HR multiple times to know the result. No reason, no explanation was given for the rejection. Really reflects the sad state of IT sector in India.
