Tell me about an experience where you were forced to handle a conflict, and what was the outcome

2 Answers

I mentioned a conflict with a teacher, and was truthful about the outcome, regardless of it's neutral (not positive or negative) tone

I gave an example of a conflict I had with a team member who was not carrying his weight in a group project. In these kinds of questions make sure to focus on your communication skills in being able to diffuse the issue and coming to a positive or neutral solution. For me, I had an honest conversation with the team member and gave him a chance to explain his situation (didn't want to jump to conclusions). Then we worked together to form a plan to ensure he met deadlines.

They presented a demo page and asked me to streamline it to make it more interactive and presentable for a user (open to interpretation).

I have a log that consists of more than 100 million lines. Each line is just a data about user login, login time, etc. I want to sort them based on user login, and then if there is a tie based on login time, etc. However, I have limited memory, so don't think of storing all of them in an array. The memory can only hold n data where n is much smaller than 100 millions. You can access the disk though although it is much slower. How will you do it so that it is as efficient as possible?

One of the software engineers asked me the question about the colored chameleons bonking into each other question. Basically, there are 15 red, 17 green, and 19 blue chameleons on a desert island. Whenever two chameleons of different colors collide, they both become chameleons of the third color. Can it ever be that all the chameleons on the island are the same color?
