Typically, the interview process tests the coding and design abilities of candidates. Additionally, it also assesses the behavioral attributes and responses in the workplace of candidates, as well as their professional experience scope. 

Essentially, the interview process comprises about three rounds. The initial phone screen with a recruiter begins the process, and this is followed by the technical phone screen which is conducted remotely, and lastly the on-site interview.  

The on-site interview usually includes a coding, design, and behavioral round, which are tailored towards testing your programming capabilities and how competent you are for the role. 

While preparing for the Google interview there are some topics to be covered, to put you in an advantageous position. There are three major parts and they are:

The Coding Aspect – Here, your proficiency in core DSA is assessed. The recruiter will typically give you a problem or two to solve during the technical phone screen and onsite interviews. The aim is to test your attitude to the problem and how the ideal solution is gotten. To prepare for this aspect, you will do well to cover the following topics: Arrays, Strings, Linked Lists, Sorting Algorithms, Recursion, Trees, Graphs, Dynamic Programming, and Hash Tables.

The Design Aspect – This is usually during the onsite interview, and your overall design proficiency is evaluated.  Note that this aspect is of greater importance for senior roles. For this aspect, the following topics should be given due attention during preparation: Network Protocols and Proxies, Sharding Techniques, Caching, Database Management Systems, Latency, Availability, and Throughput, Load Balancing, Polling, SSE, and Websocket, and Queues and Pub-sub.

The Behavioral Aspect – This is the assessment of your attitude, conduct, and the knowledge you have garnered from your past experiences and projects. Questions here are around the following areas: Google’s company culture, Workplace-related situations, Relationships with coworkers and superiors, past projects, and experiences.

Week 3

Spillover from weeks 1 and 2 should be finished here. However, it is highly recommended to devote this week to the preparation of your systems design interview. Keep at working out 3 problems daily, while practicing coding on a whiteboard.

Furthermore, it is wise to train with industry experts on attempting mock interviews. You can utilize the various online materials to make the most of your training.

Week 4

Revision on concepts of programming language. Practice responses for the behavioral interview, arranging your answers using the STAR format. A good job portfolio creation is also important here.

The following tips can be injected while studying to make the most of your preparation:

  • Break your studying into sessions and ensure to observe periodic breaks, to avoid undue exhaustion.
