Infosys Specialist Power Programmer interview questions

After my internship, I took part in the Power Programmer interviews. It was comprised of two interviews. One 3-hour technical interview with 3 Leetcode easy-medium questions. Following that, there was a 1-hour system design interview. I was made an offer in January and continuously told that I would be given a contract. I was supposed to join in September, and in August I was told that my position was no longer available. They offered a different position with a 50% salary decrease which made living in London impossible without any other financial help. I declined that offer. The offer did not have a subject area nor a role description. Such a waste of time. P.S. The recruiters only engaged quickly once I declined the second offer. They replied with 13 minutes, while they usually took months. Also, they did not use email but WhatsApp.
