I give them mock interviews and take notes of the process they went through as well as the questions they were asked. "text": "A ‘random forest’ is a supervised machine learning algorithm that is generally used for classification problems. Every time the agent performs a task that is taking it towards the goal, it is rewarded. It will make a move (decision), check if its the right move (feedback), and keep the outcomes in memory for the next step it takes (learning). Based on your experience level, you may be asked to demonstrate your skills in machine learning, additionally, but this depends mostly on the role youre pursuing.
