Applications Engineer Interview

Application

I applied through a recruiter. The process took 6 weeks. I interviewed at Google in Jan 2022

Interview

Apply online and get rejected. Then a recruiter reaches out. The first round includes 2* coding, and the final round is 1 * System Design, 1 * behavioral, and 1 *round integrated system

Coding :-

First 2 rounds will be of coding and purely based on DSA. you can expect questions on Strings, Arrays, Stacks, Queues, Trees and Graph(not much).

Now, here is the most important tip. The interviewers don’t expect a highly optimized code, that can be executed for tons of test cases. A complete solution is enough, covering all the edge cases as many as possible, like Null checks etc. But that doesn’t mean, you should not optimize it. If you have time, go for it and gain some more points. 🙂

The level of questions would be Leetcode’s Medium problems. Also, geeksforgeeks is must.

Questions asked to me were on Trees, Stack and graphs. Some of them are,

Once you clear both the coding rounds, You are eligible for next 3 rounds.

This round checks your ability to build a highly scalable system. Systems like, Movie ticket booking like BookMyShow, or E-commerce like Amazon or Flipkart, or a Search engine like Google. Don’t worry, they won’t expect you to build any system end to end.

Then, What do they expect?

The basic Idea behind this round, is to understand, how does a given system should be built according to you. The solution need not to be the exact replica of any existing system, but it should serve the purpose. For example, If they ask you to build a online food delivery system, it should not be the exact replica of Zomato/Swiggy. You can be creative but at the same time, your thoughts should make sense. You are supposed to discuss,

  • What could be schema design? — you can take a section of the whole system and discuss it’s schema.
  • How many components will be there in system, and how do they connect?
  • What technologies will you use? — for backend, frontend, middleware, etc.
  • How would you rectify scalability issues? — Always consider volume of data and concurrency.
  • Now, the important tip here is, You can ask the interviewer about, how should you proceed with the problem.

  • Start from scratch and design the whole system — you can start gathering the inputs from interview about the system, like what features they need and so on.
  • Design a part of it — Like schema, or Frontend, or APIs and so on.
  • Most of the times, interviewers leave the choice on you, in that case, go for 1.

  • make sure to read out loud while writing,
  • keep on discussing the thoughts with the interviewers, otherwise you might lose them.
  • whenever you take any assumption, just write it down
  • You are supposed to use google doc and google draw(for drawing) for writing and clip arts. So make sure to practice on these only.

    Question asked to me was system design of Walmart and ability to generate quarterly, weekly, monthly, and yearly revenue report across globe based on region.

    Application Review & Shortlisting

    When I got the initial email to check my interest in the role, I was asked to fill an Interview Availability Form.

    The form asked for the times when I’m available to take the interviews in a span of 10 days in the second week of December along with my preferred programming languages.

    Two days later, I got a mail saying Ive been shortlisted for the interviews and mandatorily need to take part in an Interview Prep Session. The session took place in the next week.

    Application Engineering? What’s that?

    It was not the first time I was hearing the term Application Engineering, but my initial perspective about the role was a bit off. Like, everyone, I was applying only for SWE roles till now, never thought of going in the AE direction.

    When I dug deeper into the role and read more about it, not only I found it more exciting than generic SWE roles, also I found it to be more aligned with my interests and my career perspective.

    Application Engineering is more business-aligned and generally focused on building products for fellow Googlers rather than for public release.
