Thinking of accepting a data science or analytics role? From startups to Big Tech, there are critical questions you must ask before signing that offer letter. In this video, I share 15 hard-earned lessons from my own experiences as a data scientist—covering everything from evaluating company culture, spotting red flags, understanding data infrastructure, assessing layoff risk, and navigating career growth.
Whether you're a data analyst, data scientist, ML engineer, junior or senior, these insights will help you make smarter decisions and avoid common pitfalls in your tech career.
Do they have data—and what kind?
How is the data structured—and who’s responsible for it?
What tools and tech do they use, and are you set up to work with them?
Does the role’s title actually match what you want (and know how) to do?
Who’s on your team—and where do you fit in?
What does your hiring manager think the ideal candidate looks like?
What does career growth look like in this role?
Who’s your manager, and can you actually work with them?
Who owns your backlog, and how is work prioritized?
Who are your stakeholders, and what’s it like working with them?
What’s the real company culture—and do their values actually show up in practice?
What’s your total compensation, and do the benefits actually matter to you?
Will you actually get the tools and equipment you need to do your job?
What’s the company’s financial health—and are layoffs a real risk?
What does your gut say?

After eight years in data analytics, spanning five companies and an entrepreneurial effort, I find myself back at King—where my career started. Looking at my career moves, I’ve started questioning whether they actually helped me progress or if they set me back.
In this video, I reflect on four key career missteps: leaving King instead of pushing for promotion, taking a career gap after my layoff from Spotify, underestimating the impact of job titles and formal roles, and not being strategic enough in planning my career trajectory. I also discuss the role of luck, timing, and how external perceptions influence career growth—sometimes more than actual performance.
The truth is, even if I had done everything “right,” it wouldn’t have guaranteed anything. If you’ve ever looked back at your career decisions and wondered if they were the right ones, this one’s for you.

The data analytics job market in 2025 is a whole different game compared to 2020. I'll talk about where I’ve been, why I left my job, my experience job hunting twice, and why I ultimately decided to return to King.
✅ Why I originally left King & my startup experience
✅ How I approached job searching in today’s market (startups vs. big companies)
✅ The biggest changes in data hiring since 2020 (fewer jobs, more interviews, less pay)
✅ What actually helped me land a great role in 2025
✅ Why I chose to come back to King and what makes it the right fit for me
If you’re currently job hunting in data analytics, data science, or product analytics, you’ve probably noticed how much harder it’s gotten. Fewer roles, longer hiring processes, and companies expecting more while offering less. I’ll share what I learned, what worked for me, and how I navigated it all.
💬 Have you been job hunting recently? What’s been your biggest challenge—fewer job openings, endless interviews, or lower offers? Drop a comment and let’s discuss!

After playing around with ChatGPT for all my SQL wants and needs I decided it could be fun to make a video, where I ask it to do a few exercises, answer questions, and write queries typical for data analysis work and interview processes.
An important disclaimer: I think it may get better with more precise and detailed prompts, however, when I started learning how to write proper prompts, I realized that writing the query myself would be easier for me. The outcome didn't seem too enticing for me to invest so much time into fine-tuning the prompts.
So this is a raw experiment, on how a human can ask questions about SQL to ChatGPT.
Enjoy!

Hi all!
Wanted to give you an update on food prices in Stockholm, after I made this video about Stockholm prices. https://youtu.be/IlA2d44cYT0
Inflation is at full speed here, and the most I notice that on food prices. SO here's a little something on how much we spend on food/eating out during a week in Stockholm, as usual, you can check the prices out yourself if you look at the websites of the stores I mention in the video.
Cheers!

Controversial topic alert!
A lot of people seem to think that being hired as a Data Scientist means that you'll deploy Machine Learning models and research AI applications. But in many companies that's not actually the case!
Here I am reviewing requirements and responsibilities for "Data Scientist" roles in some of the FAANG companies, choosing those as a proxy for big tech companies with a lot of data to play with.
The reality is that what you will actually do at your job depends more on the size and data maturity of the company than the name of your role.
As a rule of thumb, unless ML IS THE PRODUCT, in smaller companies "Data Scientists" will do all things data, often falling into Data Engineering, Analytics, and Product/Project management.
The bigger the company - the more roles are diversified, there you can find specialized ML Engineer, AI Researcher, and similar roles.
Yet, many companies still want to hire people who know advanced Statistics and ML as Data Scientists, even if they haven't reached the relevant level in the data hierarchy of needs ¯\_(ツ)_/¯.
If you want to make sure you will apply your ML knowledge at your job on a regular basis, not just when you find a rare opportunity that fits business needs, look into Machine Learning Engineer/ Software Engineer / AI Researcher roles like those: (relevant as of August 2021)

Data Scientist roles for comparison require advanced statistics knowledge, but not necessarily applied knowledge of Machine Learning and AI:

There are some companies that break the rule, like Amazon, here they say a DS will be "Improving upon existing machine learning methodologies by developing new data sources, developing and testing model enhancements..."

I've been thinking quite a bit about what powers my confidence and motivation to achieve my goals and do challenging projects, both at work and in life.
Comparing myself to colleagues and friends, I realized that the people I admire the most for taking on risks and trying new things have a specific skill or mindset in common, they have a strong feeling that they could deal with whatever comes their way.
In this video, I will talk about how I try to nurture and grow this mindset in myself.
00:00 Deal with it
00:46 How we get this mindset from childhood
02:15 How it can stop you from progressing at work
03:16 Step one - acknowledge your achievements
04:55 Step two - try new things
