Interview with Jessika Djäknegård @ Spotify

Hi there,

Thank you very much for participating in this blog series!

Tell us your name and what is your current title?

My name’s Jessika Djäknegård and I’m a Data Scientist @ Spotify.

What are you working on right now, something exciting you can share?

Analysis of the recent Student Premium market expansion.

How did you get where you are?

I took a Bachelor in Math and Statistics at Stockholm University and got my first job at Klarna. Worked there for a couple of years and then moved on to Spotify. I’ve always been intrigued by math puzzlesand problem solving and I think that’s what’s been driving me forward.

What are the most interesting aspects of your current job?

The constant opportunities to try new things and being at the center of business development of the company.

Is there anything you would have liked to know about being a Data Scientist before starting a career in this sector?

I think, first of all, the title Data Scientist is very versatile and there’s no single definition of what you’ll do in your day to day job. Some Data Scientists are very strong on the technical side whilst others are very strong on the analysis side. But it’s always important to have good domain knowledge, that’s what’s going to make your analyses rock solid in the end.

What technologies do you believe will become the next ”big thing”, both in the short term and the long term?

In the short term, I’m hoping for better infrastructure support for machine learning. Removing friction from the pre-work in order to maximize time spent on evaluating and iterating the model.

In the long term, I’m expecting to see some AI:s starting to do their own machine learning and building models. That would be super cool but also a bit intimidating as I don’t want them to take my job ;)

Lastly, do you have any interesting books in our sector to recommend for summer reading?

I’m a huge fan of everything revolving data visualization so I’d recommend  Edward Tufte’s The Visual Display of Quantitative Information.

Thanks again for participating Jessika!
