Technical Programming Interviews
These interviews will each consist of one programming challenge, where you will be given a coding challenge similar to the ones in the online assessment, but this time with an actual SDE.
The challenges will test your knowledge of data structures, algorithms, and OOP. During the problem-solving stage, you will be asked about test cases, time/space complexity, and ways to improve the solution.
Using an online coding practice website like Leetcode to prepare for the back-end engineer interview questions on tech programming can be extremely beneficial. While practicing, make sure to include questions about algorithms, data structures, and object-oriented programming.
System Design Interview
This section will be with a Hiring Manager or principal engineer who will test your system design skills. An example of a system design question could be “Design Instagram,” in which you should:
This section is about designing the software rather than coding it. However, depending on the problem, you may have to pseudo-code at times.
To prepare for the back-end engineer interview questions on system design, you should practice software design. You should understand servers, caching, performance-related topics, databases, APIs, etc.
A "Bar Raiser" conducts this back-end engineer interview on behavioral skills, which is primarily about the experience and how one can relate to specific behavioral topics and scenarios. In an Amazon interview, for example, you will be asked behavioral questions about their leadership principles, and the interviewer will assess whether or not your answers align with the company's values.
You should prepare for this section by understanding Amazon’s 16 Leadership Principles and how your experience relates to them. Also, when you are explaining your solution, try to use the STAR (situation, task, action, and result) method to break down your answer.
After the final round of back-end engineer interview questions, you should hear back within two weeks. During the interview, your technical skills and behavioral responses will be compared to the technical competencies of the role, as well as the principles of the company, to see if you’re a good fit.
