Tips & Tricks

Mirek, IT Specialist

It’s always good to have a resume complete in terms of foreign languages proficiency, acquired skills and commercial experience. Truth is always the most important aspect, so be honest.​

You are applying for a Junior position and have no experience? Don’t worry – just add your projects’ portfolio (eg. on github) and show us what you’ve been doing so far.​

We’re looking for people open to learning new technologies, getting familiar with the financial sector, particularly insurance.

Pavlo, Developer

My top 3 tips for an interview at Sollers are:​

Don’t be afraid to ask questions and admit you don’t know the answer to a given question – it doesn’t mean you know nothing, it just saves a time for all of us​

IT knowledge at least on solid basic level is also a must. This includes data structures, design paradigms and patterns, architecture design and coding principles to name a few​

Lack or little commercial experience? Be prepared to solve some algorithm tasks
