Learn A Consistent Method For Answering Prioritization And Trade

How to Crack a Google Coding Interview – An Ex-Googlers Guide

In this article, weve outlined a step-by-step method you can use to solve prioritization questions. Wed encourage you to first memorize the basic steps, and then try solving a couple of the sample questions on paper.

This will help you to understand the structure of a good answer. This is a good first step, BUT just knowing the method is not enough, as you also need to be able to apply the steps in interview conditions.

List Of Practice Questions

Now that youve got a framework in mind, use it to practice some real interview questions that were asked in past interviews at big tech companies. Here is a list of prioritization questions from PM interviews at , , , and Lyft, according to data from and Blind.

Example prioritization interview questions

  • Imagine youre a PM at a startup that works with big data from the NHL whats the first product you would ship?
  • How do you build a roadmap?
  • How do you prioritize what to build?
  • If you have projects A, B, C, how do you prioritize them?
  • How do you prioritize in your current role?
  • You are the PM for Facebook live what features would you prioritize?
  • You are the PM for Facebook pages what features would you prioritize?
  • You are the PM for Facebook posts what reactions should we add next?

What Are Prioritization And Trade

These terms often get used interchangeably when people talk about PM interviews, so well start by clarifying what we mean by prioritization and trade-off.

Analyzing trade-offs is key to the decision making process for PMs, and so questions that involve some consideration of trade-offs will come up throughout the interview process. You must be able to identify the downsides of your choices, and why they are outweighed by the advantages. For example, when answering metric definition questions, one aspect of your answer will be examining the weaknesses of your chosen metrics, or, for product strategy questions, the disadvantages of your solution.

Meanwhile, prioritization questions specifically center on trade-offs, frequently involving product features. For example: You are the PM for Instagram posts what features should we prioritize next? Questions like this test how well candidates can identify customer needs when it comes to picking the most important features and/or building out a product roadmap. Theyre all about trade-offs, hence why they are called trade-off questions in some interview formats, such as in the the .

    How To Test If Your Preparation Is Good Enough:

    Leetcode is one platform that can give you a good insight into your preparation level. Try to achieve the below targets for at least 80% of the problems that you attempt:

    • For Medium level problems, try to solve them within 20 minutes and in two attempts.
    • For Hard level problems, try to solve them within 35 minutes and at max in three attempts.

    If you are not achieving both of these for most of the problems, youll need a bit more practice. And if you are solving most of the problems in this 20/35 mins time frame, you are very likely to clear any company that you appear for, from the DS/ Algo standpoint.

    Practice With Yourself Or With Peers

    Can You Crack Google Interview Questions?

    A great way to practice answering prioritization questions is to interview yourself out loud. This may sound strange, but its an excellent way to improve the way you communicate your answers during an interview. Play the role of both the candidate and the interviewer, asking questions and answering them, just like two people would in an interview.

    If you have friends or peers who can do mock interviews with you, that’s a great option too. This can be especially helpful if your friend has experience with PM interviews, or is at least familiar with the process. You can also find peers to practice with on our new PM mock interview platform.

    In addition to practicing by yourself, and with peers, it can be a huge advantage to do mock interviews with experienced PM interviewers.

    Automated Interviewing With Coding Challenges

    Unlike the , where the initial assessment is a phone screen, Amazon expands this assessment to sometimes include a coding challenge.

    Some interviewers prefer this method, as the performance anxiety of interacting with another person is absent, and the only requirement on your end is to write code that executes correctly and efficiently.

    This is also positive for Amazon, as they do not need to expend resources on conducting 30-45 minute interviews with candidates. Furthermore, they can also expand their reach substantially, as this process is somewhat automated.

    Oftentimes, these coding challenges are driven through an engine similar to that of HackerRank, where your code is automatically analyzed for syntactic correctness, efficiency, and correctness for the task at hand. This gives a better signal to the interviewee about how well they are performing during the interview itself.

    While all of these coding assessments will have instructions, they will often mimic those of HackerRank insofar as actually using the same submission and judging criteria.

    Therefore, it is most likely a good idea to play around with the HackerRank interface, practicing a few problems to ensure that you do not get tripped up on the interface itself. This way, you can then just focus on solving the problem.

Numerous company benefits including the ability to work remotely and competitive salaries, among others are some of the reasons that may compel you to throw your hat into the ring.

    If you are intrigued by what Amazon is offering, then youll need to be able to jump the Amazon Interview hurdle. Mastering this interview is the barrier that stands before you and working for one of the largest and most prestigious tech companies.

    A Google interview generally takes 45 minutes to one hour. At the end of the interview you are usually asked if you have any questions that you would like to ask. It is not mandatory to ask questions, but doing so is alright.

    Do not make the mistake of asking So how was my interview or how did I do. When they urge you to ask questions they usually mean questions pertaining to the company like how is the work environment, what are the work hours etc.

    So you could think about the questions you would like to ask in advance so that during the interview your mind does not go completely blank. Remember the last few words that you say are going to create a lasting impression in the mind of the interviewer and therefore you should continue to have your wits about you even after the interview questions are asked.

    Tips For Practicing Coding Challenges

    There is no shortcut or magic wand for practicing coding challenges. Here are some basic tips to guide you through the preparation stage.

    Keep time in mind. The coding interview will be timed, so its important to prepare with that in mind. If you are used to preparing under a time constraint, it will be far less stressful during the actual interview.

    Know your weak spots. As you prepare, take note of your weak spots. Everyone has them. Google has stated that they care about your thought process, so if you come up against a weak spot, talk through it. This will demonstrate your eagerness to improve.

    Know the common pitfalls. There are three big pitfalls when it comes to a Google interview: not knowing the Big-O complexity of an algorithm, having no knowledge of Googles expectations, and not articulating your problem-solving process. Keep these pitfalls in mind as you work.

    Articulate your process. Google wants to hear about your thought process. As you practice, get used to explaining why and what you are doing. Those with a clear sense of how they work stand out.

    Behavioral interviews are often overlooked by software development candidates. In reality, this is the interview that sometimes will make or break you as a candidate. Google cares deeply about their values, so if you come unprepared for these questions, theyll notice it.

    Keep Practicing Your Preferred Language

    Mastery of your chosen language is essential to succeeding in Googles interview questions. Educatives Paths provide dozens of hands-on, in-browser practice problems to help finetune your coding skills.

    Where do you see yourself in twenty years

    Why do you want to be a part of the Google family?

    How To Prepare:

    Google Interview Questions
  • Know about the processTime: Get to know the interview process from your recruiter. Ask them things like how many rounds are there, how long is each round, how many questions are usually asked in a round, etc. This would give you a hint about how much time you have to solve a problem and code it up. Lets say a company normally asks 2 simple DS questions in an hour long interview, that leaves you with almost 25 minutes per problem, with some buffer.Difficulty: Now try to look at some problems that this company has asked recently and try to gauge the difficulty level. Dont look at articles that are more than 3 months old. Companies change their process and hiring bars often and normally they dont repeat the questions very frequently.
  • Know most of the important Data StructuresYou should be comfortable with at least Arrays, Stacks, Queues, Heaps, Maps, Trees , and Graphs. Dont spend too much time on complex Data structures as most companies do not expect you to know everything but they expect you to know the basics well.- If you are books person, unlike me, one of the best books out there is Introduction to Algorithms By Thomas Cormen. – If you are not a books person, like me, there are a bunch of websites that have a lot of articles and videos that you could refer.
