FWIW: I'm not the author of the content presented here (which is an outline from Edmond Lau's book). I've just copy-pasted it from somewhere over the Internet, but I cannot remember what exactly the original source is. I was also not able to find the author's name, so I cannot give him/her the proper credits.

Are Right, A Lot

1. Tell me about a decision for which data and analysis weren’t sufficient to provide the right course and you had to rely on your judgment and instincts. Give me two to three examples. They don’t have to be big strategic decisions – could be big or small.
2. Tell me about a time you made a difficult decision and how you knew it was the right solution (probe on how they evaluated the options, if they received input, what data they reviewed, etc.)
3. Give me an example of when you have to make an important decision in the absence of good data because there just wasn’t any. What was the situation and how did you arrive at your decision? Did the decision turn out to be the correct one? Why or why not?
4. Tell me about a time when you made a bad decision and the learning from the experience enabled you to make a good decision later. What did you learn that you were able to apply?
5. Tell me about a time when you have been faced with a challenge where the best way forward or strategy

How to install Hadoop on your local Kubernetes cluster

Okey this is not the easiest way of running Hadoop on your local computer and probably you should instead just install it locally.

However if you really insist doing this here's how:

1. Install kubectl, minikube and Docker if you don't already have it. I recommend using package-manager like Chocolatey. Minikube should install with VirtualBox as default driver which I recommend. When starting minikube we should increase its memory limit since our Hadoop node's pods need at least 2GB: minikube --memory 4096 --cpus 2 start (minikube's default is 1GB). NOTE: actually the Hadoop cluster by default uses about 10GB in memory limits and about 3GB running memory. From what I looked my k8s will overprovision to 300% of its capacity limits but use far less.
2. Install helm. Then run helm init.
3. Now you
