Interview Process: How to Prepare

Invest time in preparing

It’s important for any engineer, even senior ones, to brush up on their interview skills, coding skills and algorithms. An interview is typically different from your day-to-day job. This is the first technical interview in the process, so any preparation for this interview will be beneficial for the next ones.

Practice answering many different coding questions

Practice answering a coding question with the most efficient bug-free solution without using a compiler. A few resources that offer coding questions to use for practice: Careercup, Topcoder, or Project Euler.

Write code in a simple text editor

In the interview you will write your code in a similar environment (like CoderPad) without syntax highlighting or auto-completion.

Practice by coding by hand

Coding interviews will be done on a whiteboard. Practice some of the questions with a whiteboard or pen and paper to help prepare.

Practice under time pressure

You will have a limited time for the coding question, so it will be important to finish it in time. If possible, have a mock interview with a friend to simulate the interview experience.

Go over data structures, algorithms and complexity

Be able to discuss the big-O complexity of your approaches. Don’t forget to brush up on your data structures like lists, arrays, hash tables, hash maps, stacks, queues, graphs, trees, heaps. Also sorts, searches, and traversals (BFS, DFS). Also review recursion and iterative approaches.

Think about your 2-5 years career aspirations

You will be asked to talk about your interest and your strengths as an engineer.

Prepare 1-2 questions to ask your interviewer

There is 5 minutes at the end of the interview for this.
