A person contacted me through naukri.com and said he is hiring for Applied Materials. The person who contacted me was working in a company that was recently opened, so I thought it would be a fake call, but I was wrong.

He organized a technical round where there were 50 MCQ questions. Of these, 35 were technical questions like C/C++, Data Structures, Algorithms, Operating Systems, and Networking. The remaining 15 were aptitude questions.

I solved almost 40 questions correctly. After 3 days, I got a mail for a coding round. I had to complete this test within one week, so I thought to complete the test the same day. However, they were asking for permission for camera, mic, and browser access. 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 failed in an exam (they gave some information of marks of each student).
3. Given an array with positive and negative numbers, shift all the positive numbers to the right side and all negative numbers to the left side without changing the order of the numbers. Do not use an auxiliary array.
4. Given a string and a dictionary, can you make a sentence from this string using the dictionary?

I solved 3 of them, but for the last one, only a few test cases passed.

Next day, I got a call from Applied Materials for a technical round of interview and was asked for availability. They scheduled a Microsoft Teams meeting for the next day.

The next day, I again got a call and was asked for the availability for the second round of the interview. They scheduled it for the next day.

Had a discussion about my current job, projects, HR questions, and salary expectations.

I was interviewed by a lady and she asked the following questions:

• Static and dynamic linking (explain advantage and disadvantage)
• Multithreading programming (write code)
• Singleton class (write code)
• Given a string with numbers and characters, convert the numbers into actual numbers. (If the number is very big, which is not fit even in a 64-bit operating system, then how will you handle it?) Ex. "fdgdf2h4hh5r5h6bnmb7" => 245567

I had a discussion about my current job and projects.
