Hi, I'm Charlie the current ML intern at Ought. Great to hear that you're interested in applying! With regards to your questions:

• Personally, I'm really enjoying the experience. Many of the projects at Ought test the limit of current ML capabilities so you would be working on hard problems for which you can't just use a plug-and-play solution.
• I have found the culture to be very positive. Everyone on the team is very friendly and supportive(in addition to being extremely talented).
