@chinchin31 It’s all a test to see how you answer it. They don’t actually want to know your greatest weakness. They want to see if you’re intelligent enough to turn a weakness into a strength. For instance, if someone in digital marketing asked me, what my greatest weakness was, I’d answer: My greatest weakness is that I’m a sucker for the latest technology, I’m always keeping up to date with the latest gadgets and software and it’s something I truly enjoy. (Something a long those lines)
To answer the OP I think a great way to answer greatest failure would be to use something light yet resourceful to the company. Like say, you were offered a leadership position in the past but had to turn it it down because you were too determined to finish school (see, trade a + with a +) OR say something a long the lines of, “I wish I had asked my prior manager if there was anything more I could have done because I felt underutilized) [A jelly actually helped me with the underutilized thing and I used it in my interview and talked about how my skills would help this company and how I was underutilized at my prior position]
It’s important to know that you can kind of kill like 3 birds with one stone by them asking one question. It’s all about how you web the answers together. It’s true you don’t want to take too much control of the interview, but I’d say each answer should have at least one example of what you’re answering. If you answer one sentence answers you’re probably going to be too robotic for the company or come off as unprogressive for the company.
And take the YouTube “Interview Simulations” they help, and be prepared for all of a sudden panel interview. It happened to me I had to pull pages from comm. 103 haha. Plenty of eye contact and make sure you’re engaged with everyone. Most importantly be enthusiastic, don’t be a stiff, be yourself and let the interview flow it’ll be over in like 7 minutes max haha.
