How To Answer System Design Interview Questions
First and foremost, the system design interview is designed to evaluate your capability to produce technical solutions to abstract problems. As you can probably already tell, system design interview questions are meant to simulate the real-world problems candidates would tackle in their roles.
As such, they’re not designed with a specific correct answer, nor will hiring managers be looking for one. Instead, interviewers use these types of system design interview questions to evaluate how you think and approach solving complex technical problems.
You must explain the various options or paths a potential solution can take, along with the tradeoffs and drawbacks of each.
Believe it or not, system design interview rounds are usually incredibly influential on which level you are hired if you receive an offer.
Despite how influential these interview questions are, don’t be nervous! Instead, use this framework to ensure you answer the question as effectively as possible, both in practice and real life.

Possible user problems:
- Easy to sleep through or fall back asleep after alarms
- Users frequently forget to set the alarm until they are already lying in bed
- Sound disturbs others sleeping in the same room
- Voice control to set alarm from bed

How Do You Communicate With Executive Leadership
Communication is an imperative skill for Product Managers. They need to convey project information to executive leadership, partners, teammates, and other stakeholders. The interviewer wants to know how effective you are as a communicator. Mention some of the points that you keep in mind while speaking to leadership and which make you a better communicator. Few examples of these skills are:
- Be proactive: If there is a problem at hand, try finding a couple of solutions before you raise the issue in a stakeholder or leadership meeting. The issues will be better received if you include a potential approach plan in the discussion.
- Be empathetic: Get into their shoes. The executives are like your customers. Think about what information they will require like project costs, risks, schedules, etc.
- Keep it short and simple: Communicate the maximum information in minimal words. Whether it is email communication or a meeting, use short and crisp sentences and make the most of the executives precious time.

How Would You Figure It Out
Product managers need data and metrics to make good decisions and gain the support of stakeholders. This often requires doing some research to develop the right facts and figures to make their case. Asking a candidate how they would find a fact they dont already know will indicate whether they can enter a query into Google and do the up-front thinking on the right questions to ask and explain how they got there.
Can You Name Some Metrics For Measuring System Performance
Interviewers may ask you this question to find out if you understand the different ways to measure system performance and the importance of these monitoring techniques. When you answer, explain how these metrics help ensure a fast and efficient system.
Example:”The three most common metrics used to measure a system’s performance are availability, latency and throughput. These metrics help system designers measure the speed of a user’s experience while interacting with a system. Availability shows us how often a system responds to a user in a ratio of Uptime vs. Downtime. Latency refers to the speed at which a message is delivered in milliseconds. Finally, throughput measures the amount of data that successfully travels through a system to a user in a specified time period. Throughput is typically calculated in bits per second.”

Tell Me About A Product Feature That Didnt Work Out What Would You Do Differently Now
If youre an ambitious product manager, its almost inevitable you will launch some duds. Thats why Riechers asks candidates to tell about a product feature that didnt pan out. What would you do differently now?
Heres Milos riff on the theme: How do you handle situations where things are not going smoothly? Lets dive into some examples and discuss.
Self-awareness is at the heart of a good response.We all make mistakes, Riechers said. How did they deal with them? Did they take responsibility for poor outcomes? How do they treat their teams? Do they have a bias toward action? What did they learn that makes them a better PM now than before the failure?
Haar, who has a similar question in his repertoire, said assigning blame is never the right approach. A bad answer to that question is, my work was great, but this other person screwed it up. I mean, for lots of reasons, not the least of which is a lack of self-awareness, thats not really an acceptable answer. But more importantly, as a product manager, youre often leading without authority, and thats why those relationships are so important.

Can You Share A Lesson From Your Last Product Launch
As a Product Manager, each of your successful or failed product launches brings you a step closer to tried and tested methods. Your last product launch must have taught you some great lessons which you can discuss with the interviewer.
Few examples of such lessons are:
- Create an awesome team: It is not you but the team that decides the success or failure of the product. As a Product Manager, you are responsible for creating a great team. Finding out everyones strengths and utilizing them, fixing the weak link and taking tough decisions within the team are some important qualities needed in your job. With each product launch, you must be realizing the importance of having a perfect team that complements each other. Remember to highlight this in your interview.
- Stay focused: With so many products and tasks in hand, it is human to sometimes lose focus or divert to other low priority tasks. The product launch might have reminded you how important it is to focus and not let negative self-talk affect you.
- Embrace critical feedback: Constructive criticism when embraced can help you improve on your product. The product launch might have given you a chance to hear and ponder over the positive criticism and gives you a perspective to try and understand the problem from the users point of view.
