Some subjective tips on how to easily increase your chances of getting a great job after a technical interview for software engineering positions.

Words “Tech interview” build from Scrabble blocks

A technical interview is one of the most important factors in recruiting for software engineering positions. The reason for that is quite obvious — it checks what we need from programmers: the ability to solve problems, knowledge of data structures and algorithms, communication skills, etc. On the Internet, you can find countless typical interview questions for all languages and levels. However, since I started conducting technical interviews I’m still surprised by how a small number of people prepare for a technical interview. And I mean a whole interview — not only how to code some lines in a given programming language. Even a few hours spent on preparations can have a huge impact on the results and open for you a door for a dream job. So why do so many people neglect it? I believe some of them just don’t know how to prepare. If you are in that group — don’t worry! Below you can find some of my subjective tips on how to easily prepare for technical interviews and increase your chances of getting a good job. Interested? Let’s start with actions you can take before an interview.

Before interview

“Plans are nothing, planning is everything” — those words said by Dwight D. Eisenhower are still actual, even today, many years after his death. For obvious reasons you don’t know which exact question will be asked during your interview or which data structure will be needed to solve a problem. Nevertheless, you can (and you should) prepare yourself before an interview. There are many websites with typical programming tasks where you can practice — like Hackerrank or Leetcode. There are awesome, but the majority of candidates already know how to use them so I will not describe them in detail in that article. It’s enough to mention they contain many programming/algorithmic problems in different programming languages and on different levels. You can practice problem-solving on them writing your code in an interactive workspace and checking solutions via automated tests. If you don’t know them yet, you…
