I received an initial 30-minute call discussing simple things like:

• Where do you prefer to be (location)?
• What team do you prefer?
• Are you willing to relocate?

Then, I received other questions, such as:

• What makes you a better candidate than others?
• Tell me about yourself.

Finally, after this, I received a couple of technical questions that required a calculator. I had to work through them and ensure my understanding of each question was perfect, as the other questions built off the initial ones.

If you have a closed volume container and the temperature increased from 30 Celsius to 60 Celsius, what was the change in pressure and was it an increase or decrease?

Give your answer as a ratio.
