I too am going to be going through this Internship but not until next summer. I researched it quite a bit online and you can find a lot of questions all over so I just made a list and practiced answering some. Most of the questions are like TL interviews or any promotional interview, a few are different though. Here are some possible ones off the top of my head:
Describe yourself
Why do you want to work for Target
If you’re not selected as an Intern, what are some positive takeaways
Tell me about a time you worked on a project
Tell me about a time you lead a team. What worked well
Tell me about your past accomplishments (school or work)
Tell me about a goal you didn’t achieve
Tell me about a time you were stressed and how you handled it
Tell me about a time you had to adjust to a situation quickly
Tell me about a time you had to make a difficult decision
Tell me about a time you had to motivate a team member
Tell me about a time you had a problem with a co-worker and how did you resolve it
Tell me about a time your leadership skills led you to make a bad decision
Very vague but if you research it online you can find a lot of helpful information, Good luck and if you do it this summer I would love to get some feedback!
