Microsoft Interview Expertise – GeeksforGeeks


Pre-Internship Drive: Microsoft internship was top-of-the-line issues that occurred to me throughout my faculty days. It got here throughout that point of my life once I was struggling to attain something concrete. In 2019 summer season I used to be collaborating in GSOC initiatives from 2 organizations. That summer season was very hectic as my mentors had been from totally different time zone than mine which led to a messed-up sleeping schedule. After giving my all to the GSOC initiatives it was on the outcomes day that I bought to learn about my rejection from the place. It was the second consecutive yr I had did not get into GSoC. You may learn extra about GSOC right here https://summerofcode.withgoogle.com/.

It was throughout that summer season I had firms coming to my faculty for internship roles. I had round 2 months to arrange and I had zero motivation for it due to the GSOC failure. As it’s generally mentioned, Successful just isn’t all the things however desirous to win is, I began my preparation for the upcoming internship drive. I used to be not going out with pals as a result of I needed to present all of it I had.

Throughout Internship Drive: I’ve had sufficient preparations accomplished earlier than the internship drive and was prepared for what could come. Uber, DeShaw, and Goldman had been the primary firms to go to our faculty. Goldman had 30 mathematical questions and a pair of coding questions whereas Uber and DeShaw had 3 questions every of their coding spherical. Out of those three, I bought shortlisted in DeShaw for additional interviews.

DeShaw took three rounds of interviews on-site for all of us. The DeShaw workplace was large and this constructed the strain on me to show myself. The primary two rounds had been round DSA and the third spherical was system design based mostly. The primary spherical of questions was fairly simple, first, they requested me to code BFS and as a follow-up query, they requested me what high type is and requested me to code it.
They requested me a complete of 4 coding questions out of which I clearly keep in mind one as a result of it was the deciding query for my subsequent spherical choice. 
The query was: 

  • Given a keyboard with all of the alphabets from A-Z and shift and caps lock. For any given string S, what are the minimal keystrokes wanted to sort utilizing the given keyboard?

Within the system design spherical, they requested me to design a raise and requested me follow-up questions on what occurs if as a substitute of X knowledge construction we used Y knowledge construction.
After three rounds we had an HR spherical the place 3 out of ~20 shortlisted candidates bought chosen. HR was all about figuring out the DeShaw tradition and having a dialog about what they anticipated from us and telling us what we must always count on from them. All of us thought that we’re those who’re getting the internship provide. It was that night the outcomes had been out and solely one in all us three bought the internship. My failing streak continued.

Submit-DeShaw, JP Morgan, and MotorQ got here the place I used to be not eligible to take a seat due to the CGPA cutoff standards. Subsequent on the playing cards was Microsoft. I used to be all pumped and low on the identical time for the Microsoft coding spherical. Microsoft coding spherical had 3 coding questions on a portal known as Mettle. The portal was very disappointing however the questions weren’t. Individuals bought random 3 questions from a set of 500 questions. I bought two questions on hashing and one on DP. I used to be joyful once I got here to know that I had cleared the coding spherical. Microsoft got here on campus and there have been 5 rounds of interviews to observe the coding spherical. The primary spherical was often known as Group Flyer the place all of the shortlisted candidates must code the answer to 2 questions on the paper. 

Group Flyer Questions: 

  • Code fast type
  • Given a weighted graph, discover the minimal distance between two nodes.

The next 4 rounds had been largely about strings, graphs, and system design. The questions are given beneath:

  • Discover the longest Ok distinctive characters in a substring.
  • Given two strings and a legitimate operation to proper shift, left shift, take away or add a personality. Make the strings the identical in minimal operations.
  • Given a weighted graph, every weight is the price of eradicating the sting. Make the graph acyclic with minimal price.
  • You could have an infinite stream of information coming. Inform which is the primary alphabet that’s repeating. 
  • Design a textual content editor. What are the fundamental issues to remember whereas designing a textual content editor?
  • Design a pen. Listing the important thing issues whereas designing it.

I cleared all of the interview rounds and was capable of land at Microsoft for a summer season internship. Microsoft interviewers may maintain the interviewees calm and the setting relaxed. One factor that I attempted to regulate all through the Microsoft interviews was my pleasure. I attempted to not get excited after any interview spherical whether or not I excelled in it or not. It was after 4 months of steady failures, I lastly bought some success.

Learnings: Listed here are a few of my learnings from this journey.

  • Any product-based firm emphasizes problem-solving abilities greater than every other ability from an undergraduate.
  •  Giving interviews is an artwork. You shouldn’t solely have the ability to remedy issues but in addition present mushy abilities like being a group participant, communicator, chief, and so on.
  • Data with out the power to show it’s ineffective. It is best to have the ability to show your data and top-of-the-line methods is by writing good resumes.
  •  Onerous work pays off, it may be a bit late however it’ll by no means be. I consider {that a} failure just isn’t somebody who failed, a failure is somebody who failed and didn’t attempt once more.
