Mindfire Solutions General Intern Interview Questions
& Process

My suggestion is do not worry about other rounds - just focus on the 1st round which is a Coding round. It contains 5 coding questions you can solve using Java, C, C++. If you solve 4 questions correctly, you will get selected. The first 3 questions are super easy (like Area, Prime number calculation). The last 2 questions are hard, and they are 100% String and Array based. Prepare all String and Array questions. Don't worry about other rounds. Time allocated is 2h 10 min. Total marks are 110. 1st Question - 5 marks, 2nd Question - 10 marks, 3rd Question - 20 marks, 4th Question - 30 marks, 5th Question - 45 marks. The timer starts when you log in to the editor. It's a simple editor with no test cases, but predefined methods like HackerRank. You just write the logic. If you have any problems, you can contact their support. Some methods are not allowed, so you can create user-defined methods like length. At the end, practice all String and Array questions 100%. You must know one sorting and one searching algorithm. No packages will be imported by the user. Just believe me.

We started with some written tests that were pretty easy, an aptitude test and a technical test mostly in C/C++. After that, we had a technical interview with two software engineers, focusing on basic concepts. Then, there was a more challenging technical interview with a senior developer who is the Team Manager. This one was long and tough, focusing on logic and concepts, and it was quite confusing but I managed to pass. The final step was an interview with the HR Manager, which felt like just a formality, and I think I messed up a few things. The biggest downside was the long waiting times, sometimes from 11 AM until 6-8 PM for a single interview.

It was a 5-stage interview process. The first round was a coding test with 5 questions that got progressively harder. You could use any language, and getting 3 out of 5 correct meant you'd likely pass. The second round was a psychometric test with tricky questions and a 1-hour time limit; everyone passed this. Then, there were two 1:1 technical interviews to assess technical skills. In the last one, I was asked a question I missed in the coding round. Finally, there was an HR round.
