I had an interview in German many years ago. It wasn’t for a job, but for academics. It went ok, considering I never met my interviewer before and had zero prep.
I help my foreign clients prep for job interviews very often. My service typically takes 10-15 hours, done over several appointments.
I start by having them read a rather important 2015 article by Lazlo Bock called “Win Every Interview with these 6 Steps.” Bock was Google’s SVP of People Operations. Google knows a thing or two about hiring extremely bright, competitive, and highly skilled employees.
I ask my clients questions about the article to check for their understanding. We go over vocabulary. Then I say, “Considering Bock’s advice that you’ve just read, what might you do to prepare for your interview?”
Next, after starting to form a plan, I show them a list of “performance based interview questions.” These are used in structured interviews, typically given by recruiters for giant multinationals in first round interviews (which is a job I had for 2 years). An example might be “Describe a situation in which you had to use your communication skills in presenting complex information. How did you determine whether your message was received?”
Or “Tell me about a time when you needed to convince a group of peers to follow your plan, implement your strategy, or take action. How did you persuade them and what were the results?”
After that, we use Monster’s “100 top job interview questions—be prepared for the interview”. These are very typical job interview questions.
I ask my client to write the answers to the top 5 for homework
1 Tell me about yourself.
2 What are your strengths?
3 What are your weaknesses?
4 Why do you want this job?
5 Where would you like to be in your career five years from now?
The next day I check the homework and make corrections to the writing. Then I ask the same 5 questions again in a different order. Just for practicing delivery.
Then I reverse the situation and have my student pretend to be the interviewer and I answer the questions (for myself).
Next we start going through some performance based questions. I give some example answers. Then I have my client try.
We continue doing this practice again and again, mixing typical questions from monster with the more difficult to answer performance based questions. We repeat some questions a few times for practice.
So… try practicing those interview questions in Spanish with a partner
You might want to record all your practices too, so you can listen and analyze them later
