Applied Materials interview questions

A person contacted me through naukri.com and said he is hiring for Applied Material. The person who contacted me was working in a company which was recently open so thought it would be a fake call but I was wrong. He organized a technical round where as 50 mcq questions were there in which 35 of them are technical question like C/C++, Data structure, Algorithms, Operating System, Networking. And 15 of them are aptitude questions. I solved almost 40 questions correctly. After 3 days I got a mail for coding round. I had to complete this test within one week. So thought to complete the test same day. But they were asking for the permision of camera, mic and browser access but my laptop camera was not working so I changed my laptop camera within 2 days and completed the test Questions 1. Print the pyramid using characters. 2. How many students got failed in a exam(They give some information of marks of each stutent) 3. Have an array with positive and negative number shift all the positive numbers right side and all negative numbers left side without changing the order of numbers. don't use auxiliary array. 4. A string and a dictionary is given can you make santance of this string using dictionary. I solved 3 of them but the last one only few test case got passed. Next day I got a call from Applied Materials for technical round of interview and asked for the availability. they schedule Microsoft Team meeting for the next day. Next day I again got a call and asked for the availability of second round of interview. They schedule it to next day. Had discussion about my current job, project, HR questions and salary expectation.

I went through 3 stages, there were two more to go. in my eyes, it went pretty well. enough to get an answer or an update even if it's negative. 2 months later I get the answer via email with no feedback. I have to say I enjoyed the process, the interviewers, and their questions. but leaving a candidate with nothing to work with for over two months is just not right. hope they will fix that.
