Amazon software engineer interview

Amazon - We Pioneer

I was recently contacted by a technical recruiter from Amazon. The company was hosting an interview event for software engineers to join a team in their Berlin office.

The whole process from being contacted to signing the contract took two months. I would like to share my experience on how it went in general as well as what I believe helped me pass it successfully.

If I failed to mention something important in this article, feel free to start a discussion in the comments section. There I will try to be as detailed as possible.

Go from PHP engineer's perspective


As a PHP engineer, have you ever asked yourself whether you need to master other programming languages?

PHP has been the language of choice for building a full-stack monolithic applications for many companies and many years. Furthermore, in the last 5 years frameworks (Symfony, Laravel, Zend), tools (Composer, Monolog) and rapidly growing community (PHP-FIG) helped many engineers to build enterprise level software applications. Many companies, such as Facebook, Yahoo!, Wikipedia, Wordpress, Tumblr, had pure PHP in their early days, and that didn’t hold them back from becoming successful over the years.

However, a successful business grows, so grows the number of engineers it needs to support the growth. Organizational structure of the company indicates that the existing monolith is better be split apart. At some point the strategy stabilizes and teams now focus on independent services instead.

In this article we will try to evaluate how far can PHP alone take us and where Go can step in and solve problems we will face down the road.

Cracking Hackerrank - Encryption

As a friend of mine loves to say, “The best way to learn a programming language is to start writing algorithms in it”. While that most probably won’t make you the language expert, there’s a high chance that you will face most of the data structures it provides as well as feel the power of it’s unique language constructs.

There’re lots of good resources to help you get started, but I prefer to spend my spare time on Hackerrank. It’s free, has pleasant user interface and a solid selection of algorithmic problems conveniently broken down into categories and difficulty levels.

After solving each problem, the whole analyzing part is usually getting thrown out. And that pointed me to the idea of writing the way of thinking into blog posts. Always good to look back and see how good you were and how bad was your English. So let’s get it started!

Our today’s problem - “Encryption” (link to the challenge).
