Data Scientist questions

What are the benefits of joining the certace network for independent data scientists?
Unlike being employed permanently at a company, freelance work brings the advantage of getting exposed to new data problems with each project. At the same time, you don’t need to spend your time on sales activities, accounting or even legal aspects. certace takes care of this so you can fully concentrate on the project at hand. Additionally, when we contact you, you decide if you want to accept a project or not. That way, you can influence how much you work and you can accept projects that interest you the most.

How is the assessment structured? Can I prepare for it?
The assessment consists of many components such as a self-assessment, actual test questions and even peer interviews, so make sure you plan enough time when you start the process. The best preparation is, of course, your academic and practical career. Questions include those on statistics and probability, linear regression, machine learning, and computer science, and there will be a practical data challenge. In the interview, we will ask you more about specific projects and your area of expertise.

I did not pass the data science assessment. Can I try again?
Sorry, unfortunately you can only take the exam once. Please contact us at support@certace.com if you have encountered technical problems during the exam.

Can I influence which projects I would like to be contacted for?
You do so automatically, based on your answers/results from the assessment. Other than that, we unfortunately cannot guarantee to take into account personal wishes.

Is it possible to only work on remote projects?
This depends on the client and the project. Obviously you maximize your chances of getting hired if you are willing to work at a client’s place of work – at least partially.

What is the average rate that data scientists can expect with certace?
The range is broad – it depends on the skills required for a specific project and if you are willing to work directly at a client’s office. We might sometimes offer you the opportunity to apply for projects where you would earn a lower rate than you might expect. In that case, it’s up to you to decide if you find the project interesting enough to accept the project anyway.

Can I recommend certace to friends?
Of course: as many as you want! We don’t have an official referral system in place yet, but we would really appreciate it if you were to tell your fellow ace data scientists about our service.

Client questions

Why should I use certace?
If you are already using data science to generate business insights, you know how difficult and time-consuming it is to find the data experts you need. certace experts don’t come with the bias of knowing your business, but instead challenge the data you are already working with. If you just want one expert, that is fine with us. We will not sell you a whole team if you don’t need it.
If you have not yet been leveraging the power of data science, there is so much that certace can provide you with. First and foremost, we take care of the whole process of qualifying data experts. Instead of working with a full service agency, you will get an expert that fits your specific project description best. Read in our scoping a data project section what needs to be specified before project kick-off.

What does a typical data science project look like?
There is no ‘typical’ project, but there are some types of challenges that most companies face and that, therefore, make great projects to develop a competitive advantage through the use of data science. One example could be predictive analysis and development of customer knowledge – e.g. if customers buy, how many times they will buy; and if they are likely to default or, more precisely, when customers will buy or default. Visit our success stories section to get more information.

How much does certace charge?
This really depends on the project and the demand for a specific area of expertise. Talents’ expectations of their daily rate also vary based on their geographical location and expertise. As a client, you are able to influence the rate to some degree – e.g. by not insisting that data science experts work on site. If remote work is accepted, most data scientists would have lower daily rates than if they have to travel.
The first seven days of an assignment are completely risk free, but usually our experts are definitely worth the money.

Where do you get your talents from?
The data science community is very well connected. Therefore, most of our talents are referred to us by our early adopters. Additionally, we cooperate with universities to maintain a pipeline of fresh talent.

What sort of data scientists are on your platform?
Our data scientists have very different backgrounds, but what they have in common is that they are aces in their respective fields. Many have a mathematics, statistics, physics or computer science background, and are extremely motivated to solve new data challenges each day. Read about some data scientists who joined the certace network.

Where are the data scientist based? Are they willing to travel?
certace is a completely global business; hence, our data scientists are based all over the world. Many of them are willing to travel if the client requests them to be on site, but to get the best match for your project we advise clients to be open minded for remote-working talents too.

Do the data scientists speak English?
Yes, all data scientists who are part of the network have had to go through two interviews and are able to communicate in English.

How do you ensure that data scientists really have the necessary qualifications?
All our data science experts must complete a multidimensional assessment when they apply to join the network. The assessment is dynamic, meaning that talents must answer different test questions based on their expertise. In the last stage, each candidate is interviewed by two peers, each of which makes a recommendation on whether the candidate should be invited to join certace or not.

How do you guarantee data safety?
All independent data experts that pass the certace Data Scientist Assessment need to sign a consulting service level agreement if they want to work on projects. These agreements are more watertight than contracts of full time employees in leading financial institutions. If required, we can also provide more background information on the data professional chosen by the client, but this will cause a slight delay until project kick-off.

Who does the intellectual property belong to?
All work created by a certace freelancer is the property of the client.

What happens if I am not satisfied with the quality of work?
While we really try to provide you with the best match for your project, we understand that there remains a residual risk that you might not get along on a personal level, or that the work doesn’t correspond to your expectations. In that case, we would immediately look for a replacement.
