“If she’s got an interview, chances are they already think she’ll be able to do the job just fine (they wouldn’t waste their time speaking to someone they weren’t sure about.”
I had an interview with a F1 engine supplier a few years ago, for what I believed to be a tribology role. I’m a materials engineer, but pretty heavily biased towards coating development and testing and the CV screams that. The job spec must have changed, as they interviewed me for a staff metallurgist, with a heavy focus on magnesium, and was told that they don’t need a coatings materials engineer. The interviewer then followed by asking questions about Beryllium metallurgy, which is redundant in F1!
I can’t believe they were sure i could do the job.
But, fingers crossed for your mrs. Best advice is to be prepared and enthusiastic, even about the most monotonous of tasks. Hope it goes well.
