Tata Consultancy Services Software Developer interview questions

It was a lengthy process. We had to wait for around 8-9 hours. The technical interviewer asked questions on os deadlock to which he gave weird solution. Deadlock avoidance practically that can be solved by rebooting the system but he was not happy with the response.

The interview was unusual. The interviewer never turned on her camera, did not introduce herself, and spoke with an accent that made several questions hard to understand. She asked me to introduce myself but gave no reaction at all and immediately moved into technical questions, such as the virtual DOM, React context, different ways to hide an element in CSS, and the types in the expression a = b = 5. At the end she asked me to open a React playground and write a small component using an input and useRef to inspect its value. When I said I had no questions, she abruptly ended the call without any closing remarks. It all felt strangely impersonal and abrupt.
