They make agricultural robots for easing farming. They have a bunch of robot to remove weed

This is plain wrong. One of Ada's favorite niche is real time embedded systems with a strong emphasis on safety and reliability. It is widely used in aerospace, railway, ...

- How do you handle a young developer who is making mistakes ? Do you take time to help him ? A concrete example would to give him/her a bad piece of code and ask him/her to peer-review it.

- Are you ready to give some talks about whatever your are good/expert at ?

- What is your attitude toward optimization (I would expect something like : don't optimize until it is correct and needed, but don't write the original code without performances in mind).

- Check if the candidate is stubborn. A senior grumpy stubborn developer can be a pain to work with.

Bonus: what is the job ?

Remember that many scientific papers published in peer-reviewed journals turn out to be wrong/not reproducible or contain errors .

Remember, we are already using super sensitive telescopes for looking at the star nearby the exoplanets.

To propel a spacecraft, due to the law of conservation of momentum, if you want to go in one direction, you have to push something (the propellant) in the opposite direction.

It's the momentum of the ejected stuff (mass*velocity) that matters for maneuvering in space. You have to carry that propellant with you and accelerate it. You can use specific impulse to compare efficiency of rockets (the higher, the more efficient is the rocket in creating forward thrust with the same amount of propellant). The best engines we have are ion thrusters because we can accelerate a small amount of gaz (not very heavy to carry) very fast => big momentum. But thrust is limited, this why you can not lift off from Earth with an ion thruster.

Nuclear energy is just used to power spacecrafts in electricity when you can't use solar panels.

From a traveling point of view, sending a probe to Pluton (New Horizons) took us 10 years and the probe had a nice pull from Jupiter. The closest exoplanet is 6 700 times farer than Pluton.

From a communication point of view, the probe/rover would not be able to send us back any kind of signal. Even if we were able to communicate, a round-trip message would take 8 years.

And remember, we are not always successful when sending a probe/rover to Mars, which is the closest planet to Earth.

It is not specific to any language and it gives a grade on many many relevant aspects of everyday programming (IDE, automatic build, framework, data structure...)

Once all expenses are taken into account, I think that US salaries are higher but not _that_ higher.
