Recruitment process

If you have already applied for a job at Allegro or would like to ask about further steps read on to get more insight on the Allegro Tech recruitment process.

Home Assignment

Home assignment

As a home assignment you are to write a simple REST service that meets given requirements. Task difficulty has been calibrated so that it can be completed in 4 to 5 hours of work, with a total of a few hundred lines of code. You submit the task in form of a pull request reviewed by an Allegro engineer. This reflects our daily practices when working with code and gives you the chance to explain the design or even apply some fixes based on our engineer’s suggestions.



During this part of the interview process we focus on skills used in day-to-day work on a single microservice. We talk about good development practices, programming languages and known frameworks. We care not only about software quality, but also performance, reliability and metrics of our services, thus expect questions about making things fast or implementation details of your platform of choice. You might be asked to perform code review focused purely on good practices (i.e. no hunting for syntax mistakes or code parsing).


Algorithms and architecture

„Algorithms and architecture” is a conversation about more abstract and high-level aspects of programming. Our starting point is designing a system which adds a new feature to Allegro (proposed by the interviewer). We pay attention to problem-solving skills and ability to think about the whole system from both user and technical perspective. Knowledge of specific technologies, while a welcome addition, is not as important as those abilities. We ask questions about scalability, performance and fault-tolerance of designed system.



During this interview, we evaluate a candidate’s soft skills, including communication and teamwork skills, focus on usability, analytical thinking and work motivation. Moreover, we assess a candidate’s cultural fit in the workplace and to the team – whether they share similar values and are able to align to our work standards. It is likely that the candidate’s future boss will take part in this meeting as well.

  • Adam Dubiel - Team Leader @ Allegro (Warsaw)

    I joined Allegro right before the microservice revolution. From this perspective I can see how much has changed and how lucky I am to be part of that process. Currently I’m leading a team responsible for services that are fundamental to our new architecture. My job is to make life of all our developers easier and ensure that the infrastructure is ready to meet their demands. Despite exciting technologies and the huge scale, the most important thing at Allegro are the people I work with, engineers and managers from whom I still have a lot to learn.

  • Dariusz Eliasz - BigData Platform Engineer @ Allegro (Toruń)

    Since my first days at Allegro I have had the opportunity to setup and work on many exciting projects. As a System Engineer I was building infrastructural services like a log aggregation system. Later, as a Solutions Architect, I was involved in migrating our platform to Service Oriented Architecture. Now I'm engaged in a Hadoop data governance project and building our BigData stack. It proves that Allegro is a great place where you never get bored because there are always inspiring projects going on.

  • Marcin Kliks - Team Leader @ Allegro (Poznań)

    My adventure at Allegro started in April 2012. Back then I was working on a ground-breaking Open Source project – Ralph. It is a system for managing Data Center infrastructure that helped us automate work of thousands of servers and optimize the maintenance cost. I lead a team that develops software for managing servers, databases and microservices. Every day, we look for solutions that allow us to use the resources of our two Data Centers to their maximum, lower the cost and conveniently automate tasks performed in Data Centers. Our goal is to provide absolute scalability and ensure that Allegro developers can deploy new functionalities for our users in no time. Working with our infrastructure is far from mundane. When integrating various systems you have to deal with many programming languages such as Python, Go, Java and even Swift. Moreover, the scale of Allegro provides exciting challenges, where every 1% makes a difference.

  • Adam Dudczak - Technical Team Manager @ Allegro (Poznań)

    I have worked with Java related technologies since 2004, and I joined Allegro search team about 3 years ago. Developing the largest e-commerce search engine in Poland is both challenging and fun. Working as a full stack search developer can be demanding as it requires a unique blend of software development, devops and Big Data skills. I enjoy the atmosphere of restless technical curiosity which I experience at Allegro. I've never had a chance to work with such passionate developers before! You learn something interesting in terms of software and product development all the time. Moreover, I support Java community in Poznań as one of the leaders of Poznań JUG and as a co-organizer of GeeCON conference. I am a happy father of three, and a lucky man who married a very patient woman.

  • Kamil Borzym - Senior Software Engineer @ Allegro (Warsaw)

    I joined Allegro as an iOS developer when mobile apps were considered to be only hipster toys. Today, more than a half of Allegro traffic comes from mobile devices. I have the privilege of working with amazing people on one of the largest personal shopping assistant apps in Europe. Working with such a huge scale is incredible, because every little decision can impact millions of users. By getting the things right, we can make people's lives easier.

    I love low-level stuff and reverse engineering. I think it is wrong to call these things "useless knowledge". It should be the developer's personal duty to understand how computers work. At Allegro I can make use of this knowledge.
