@jakubzavrel
I like programming, but I’m interested do take on more project
management responsibility
Is there a job in our organisation that better fits my degree?
I’d like to work on our mobile strategy. I’ve helped a friend
develop a mobile app.
I’d like to do more with my organisational
talent.
We are looking to hire:
An experienced tech team team lead
Labour Market:
a Language Gap
The ideal candidate has:
- min. 5yr of experience
- Certfied scrummaster
- Exp. w/iOS, Android
Completed academic studies
Computer Science or related
30% travel for customer presentations
In the next 5-10 years, AI will reach a level of near or super
human performance in many domains, including understanding
language and connecting supply and demand.
AI will fundamentally change the way people and jobs connect
in the global marketplace, and will remove market barriers
caused by language meaning variation and lack of
transparency.

Understanding
the job
AI Revolution: lowers the cost of repetitive cognitive tasks...
AI: The miracle algorithm?
Right candidate, right time, right price!
So what if you have technology that actually understands:
• the real requirements of the job
• the key factors to be successful
• the type of person most likely to succeed
• what your offer should be
So what do we mean by AI?

Ability to solve problems with unknown rules
What does Machine Learning give us?
Pattern discovery in volumes of data no human being is able to digest
What does Machine Learning give us?
Optimize solutions to problems with any value that we can define
What does Machine Learning give us?
What does Machine Learning give us?
Any human behavior for which we can collect sufficient data can be automated
by AI / Machine Learning
AI is Mainstream
Why now? Computing power, data, algorithms
Deep Learning
Deep Learning is the ability
for AI algorithms to automatically
learn meaningful patterns in
data using layered brain-like
structures called
Deep Neural Networks
Deep Learning: Hierarchically abstract information
• Use lots of unlabeled data• Deep multi-layered networks• Automatically finds relevant features
Understanding, connecting and analyzingpeople and jobs
Given a job, how do we find the relevant
candidates for the job among thousands or millions of CV’s?

Example of Matching
Turning the job description into a rich query
Learning from Feedback:
• Which candidate is the best?• Which criterion is more important?
• How about combination of criteria?
• How about domain biases?
• What if we can learn this automatically from feedback?
• Learning to Rank• Reorder a pool of candidates through machine learning
• E.g. Based on recruiter preference or past performance

Remember: it’s all measurable!!!
Fairness? Bias?
Explainability?
