Microsoft Software Engineer Roles and Responsibilities

Software engineers are called the Keepers of the Code at Microsoft. Before getting into the interview process, let’s look at the roles and responsibilities a Software Engineer at Microsoft is expected to perform:

  1. Build data structures and algorithms.
  2. Write quality code.
  3. Explore and implement innovative technical solutions to problems.
  4. Test and debug code.
  5. Actively contribute to feature definition and design.
  6. Assess feature feasibility and estimate its development time.
  7. Work with cross-functional teams to meet deadlines.

What Exactly Does Microsoft Look for in Software Engineers?

Whether you are interviewing for the position of a Software Engineer, Software Developer, or a senior role like an Engineering Manager or a Senior Software Engineer, some core value expectations from you will remain the same. 

Microsoft is looking for software engineers who will bring more to the table than just coding skills. Microsoft believes in finding excellence in simplicity, and therefore looks for the following two qualities in their hires:

  1. People who truly believe in Microsoft’s products and align with its mission.
  2. People with high potential as compared to those who already come with significant accomplishments on paper.

Microsoft Software Engineer Salary 

According to Comparably, a Microsoft Software Engineer earns $136,877 annually. 

This includes a base salary of $121,962 and a $14,915 bonus. The annual salary can range from $74,000 to $188,000. The offer you receive will be based on many factors, such as your skillset, experience, and the value you bring to the organization. Your final package will depend on how you perform during the interview and how well you negotiate.

Tips to Negotiate Software Engineer Salary at Microsoft

Negotiating one’s salary can seem daunting at first, and many candidates are uncomfortable doing it in fear of spoiling their chance of getting selected. Here are a few pointers you can keep in mind while negotiating your package:

  • Do not share your current compensation with your interviewer.
  • You are not obligated to share the compensation you are expecting.
  • Build a good rapport with the hiring manager.
  • Do not insist on receiving offers in writing.
  • Check with your recruiter and ask for a relocation package if it applies to your case.
  • Remember to compare your offer with publicly available data.

Salary negotiation is a must-have skill for any role. Read The Ultimate Guide to Salary Negotiation at FAANG for Software Engineers to hone your negotiation skills and get an offer that matches your value.

Microsoft Software Engineer Interview Process and Timeline

A Microsoft Software Engineer Interview Process takes 4-8 weeks to complete. Microsoft receives a huge volume of applications and wants to make sure that you are interviewed for and placed in the right division based on your skills.

The Microsoft Software Engineer interview steps are:

1. Getting the Interview

2. Round I – Phone Screen

2.1. Recruiter Screening

2.2. Online Coding Assessment

3. Round II — Onsite Interviews

4. Results

1. Getting the Interview

The first step in the Software Engineer interview process is to get an interview with Microsoft. You will need:

  • A captivating cover letter that highlights your individual story.
  • A resume fine-tuned to the Microsoft Software Engineer job description.
  • One or more reliable referrals, if possible.

2. Round I — Phone Screen

Once your resume is shortlisted, a recruiter will call you to get to know you better. A Microsoft Software Engineer phone interview is a mix of behavioral questions to see if you are a good culture fit and an online coding assessment on a remote online editor to test your coding skills as a software developer. Each phone screen lasts for around 45-60 minutes. 

2.1. Recruiter Screening

This is the first call you will receive in the Microsoft Software Engineer interview process. It is usually a phone call; however, sometimes, it may be in the form of a video call. The recruiter will ask you questions about your experience and career aspirations. A general overview of your technical knowledge may be included.

2.2. Online Coding Assessment

You can expect data structure and algorithm questions for the coding interview, which you will have to solve on a remote collaborative text editor. The editor will not have features like syntax highlighting and autocomplete, so you will need to practice coding without those features when preparing for your interview. It is unlikely that you will be asked system design questions at this stage.

Find out how to face phone screen interviews with ease.

3. Round II — Onsite Interview

If you pass the recruiter screening and coding assessment, you will be called for an onsite interview. This is a day-long process at Microsoft’s office and involves four onsite interviews. These interviews are based on product design, technical knowledge, behavioral aspects, and strategy. Each interview lasts for 60 minutes.

Onsite interviews are usually one-on-one with people from the team you’re applying to be a part of. This may include current Microsoft Software Engineers, a hiring manager, and a senior executive. Most of the interviews will be based on data structure and algorithm questions, which you will need to solve on a whiteboard. You may also be asked a system design question.

Behavioral questions will be a part of all interviews and will focus on evaluating whether you are culturally a good fit for Microsoft or not. It involves behavioral questions. Microsoft tends to spend more time on behavioral questions as compared to its counterparts like Google and Facebook. Check out the following articles for sample interview questions:

Microsoft Senior Software Engineer Interview Process

While the main interview process remains the same, the level of expectations from a Microsoft Senior Software Engineer candidate is higher. Microsoft Senior Software Engineer interview questions are the same coding questions as a software engineer, but you will be expected to do better than the lower-level candidates. Microsoft Principal Software Engineer interview questions are often based on system design and architecture.

Microsoft Software Engineering Manager Interview Process

Microsoft Software Engineering Manager interview questions are similar to those of a Senior Software Engineer, but the level of expectations is even higher. You will also be asked questions based on past experiences to assess your leadership qualities. A tech lead from Microsoft will be a part of this interview panel.

AA or ASAPP Interview

If you pass the first three onsite interviews, you will be asked to sit for an “As Appropriate” or AA or ASAPP interview. The idea behind this interview is to make sure that no blind spot is left in your previous interviews and that no aspect of your technical knowledge and skills goes overlooked. 

4. Results

If you clear the ASAPP Interview, a recruiter or hiring manager from Microsoft will get in touch with you with an offer. The time taken varies, as data aggregation and making the final call take time and depend on several factors.

  • Continuous Integration
  • Test Automation/Frameworks
  • API testing - REST/SOAP
