Tell me about a time when you overcame a challenge at work.

This question allows you to demonstrate your problem-solving skills and ability to adapt to change. When answering this question, it can be helpful to provide details about the challenge, how you overcame it and the results.

I spoke with my manager about the issue, and we decided to add the feature to the website.

I was able to complete the project within the same time frame as before, and I was able to add the search engine optimization feature. This allowed the client to rank higher in search engines.”

I also explained that DNS servers are responsible for translating domain names into IP addresses.”
