FAQs: Working at CSHARK
How should I prepare for the first interview?
Before the interview, we’ll send you a short manual that outlines everything you need to know. Above all, you should pay attention to the following:
- Take a second look at the job offer. Perhaps you have some doubts or additional questions? We’ll clarify everything you’d like to know during the interview.
- Do not hesitate to explore our website before the interview - you’ll find a lot of useful information there.
- Be prepared to talk about your past work experience. We want to know what you’d been up to.
- Be ready to talk about formalities, including the length of the notice period, your salary expectations, type of contract and any other formal issues that are important to you.
We treat every interview as a bilateral meeting. We talk and we listen, trying to keep it at 50:50, so you will have plenty of time to talk about yourself and ask questions.
hideCan I apply for work experience at CSHARK?
We don’t offer work experience placements on a regular basis. However, sometimes we recruit apprentices when new projects begin, so we encourage you to check our Careers page regularly for such openings.
hideIs it possible to work 100% remotely?
For CSHARK you can work 100% remotely, rarely there are projects where we build a team in a given location, but if it's so we always underline it in the job description.
hideWhat will my career path look like?
At CSHARK, we operate in terms of seniority, so our employees work at Junior, Mid- and Senior level positions before they can become a Tech Lead and then Architect. At the same time, no career path at our company is engraved in stone. We support our employees’ professional development and thus opportunities to advance are always being considered individually. If we notice that you progress, we will be happy to discuss promotion opportunities. If our employee wants to make a change too, we are also open to talk about it.
hideCan I switch to a different project while I work at CSHARK?
Yes, it’s possible, but it won’t happen overnight. If you want to change the project, you will have to communicate this to your Line Manager first. You will talk to state the reasons for your desire to change, as well as your expectations regarding the new assignment. It will also be necessary to find a replacement before you transfer to a new project.
hideIf I’ve been seeing a job offer on your website for a while, is it still valid?
We update our careers page regularly, so any offer that you find there is waiting for your application. If a role is related to our core technologies, i.e. C# and .NET, we constantly look for qualified staff, hence some offers (especially for .NET Developers) may be up for a longer period of time.
hideCan I apply if I don’t see an offer that matches my technical skills?
We encourage you to send your CV through Haven’t found what you are looking for? tab. We save every application in our database. When new vacancies pop up, we contact the candidates from that database in the first place. Patience is a virtue!
hideWhat’s the required knowledge level of English?
You have to be able to communicate freely within the team and with a client. There is no need to present a certificate, however, we will verify your knowledge of English during the interviews.
