Preparing for a technical interview for a #DataScience position? These are some of the questions that typically allow me as an interviewer to quickly distinguish between juniors and mediors, including some quick tips 🧵. #Python #pythonprogramming #DataScientist #Jobs
All questions about SQL. Not the hardest thing to learn, but many #DataScientists only start to learn the value of SQL when they actually become part of a dev team. I’m not only talking about SELECT * FROM table, but also about joins, truncates, partitions and constraints.
Interacting with an API. Make sure you know your requests (GET, POST, PUT, DELETE, PATCH), as well as the #Python requests library.

Yesterday I shared a small thread about getting into #DataScience. Today I’ll build on that and share a bit about my own journey into sports analytics, specifically as a #DataScientist in the #football industry. 🧵
My path began with a MSc in Sport & Movement Science @VU_FBW. It’s not computer science or anything, but it does involve quite some #Math, #Statistics and #Physics, as well as a course in programming. Mainly it learned me Science, and gave me a lot of domain knowledge in sports.
I wasn’t planning to become a #DataScientist, but I wanted to work in sports. I did various stints as an embedded sports scientist, mostly internships/part-time, before joining @ZZLEIDENBASKETB. Those jobs involved data & science, but it wasn’t anything close to #DataScience.

As an aspiring #DataScientist, one way to showcase your skills is to build interesting portfolio projects.

Here’s a guide on how to develop interesting data science project ideas & implement them.

Step 1: Choose your passion topic that is relevant.

#DataScience
Step 2: Start Scraping together your own #dataset.

Step 3: Cleaning your dataset (here’s where #datascientists spend about 60% of their time).

Step 4: Data Exploration and Analysis.

Step 5: Share your work on a blog or a popular forum/community.

Please help us welcome our next curator Darryl Takudzwa Griffiths. @BlaqNinja completed his Bachelors Degree in Computer Engineering at DUT, graduated in 2011. Due to struggling to find suitable employment he went on to study multiple certificates from bodies such as Microsoft.
He has certificates in N+ (Computer Networking), A+ (Computer Technician & Technical Support), Certified Ethical Hacking V7 (CEH v7), Offensive Security Certified Professional (OSCP). Sadly even with these, he could not secure his desired post so in 2016 he moved to USA.
Darryl was able to secure a job in a corporation that owns casinos as a system analyst & security architect. Within the same year he embarked on a Masters degree in Robotics & Artificial Intelligence Engineering. In 2017 he resigned from his post and started his own company...

"The #OFQUAL #algorithm is a gross misuse of statistics... there is a special place in hell for those who use maths to hide rather than reveal the truth, this algorithm is hiding the achievement of this generation of young people." my @ChronicleLive blog chroniclelive.co.uk/news/news-opin…
Most people now think the #AlevelResults should not stand, whether the Govt will recognise that or not is another matter. But we shouldn't blame #algorithms for this huge injustice - like most technology they are neither good nor bad in themselves
And I don't blame those who wrote the #algorithm I do think #engineers (like me) & #datascientists should take a 'do no harm' oath like doctors, but currently there is no framework for that & they were presumably working to a spec

Kom op, @rivm, maak asjeblieft een public API met de #corona cijfers! Inzicht door #developers developer.overheid.nl/apis @Rijksoverheid #OpenSource #crowd @WouterWelling @AstridOosenbrug
Voorbeeld; door @rivm data te combineren met @Flitsmeister zijn er misschien wel voorspellende modellen te maken met "hot highways"?.. Geef het aan #datascientists en de #crowd..

Why mid-sized companies are behind the #datascience curve: A thread—
Mid-sized companies are behind in terms of being data-driven when compared to startups and large entities. There are several reasons for this which puts them at a disadvantage.
1/ The average age of a mid-sized company is c years. X years older than the average startup and large entities such as Facebook or Apple. Overall, their workforce is older as well which translates into greater domain knowledge and also little technical capability.
2/ There is often a greater majority of non-technical works which places a heavy burden on the few technical workers often leading to burnout, limitations and ultimately churn.
