Technical interview questions are bound to come up when your job involves some technical content and because that includes so many different subjects, what we can only do here is show you HOW to deal with technical interview questions.
If you really know your subject from practical experience, then in any particular area, you should also be able to say what could go wrong. Other interview candidates who don't have your experience or if they had only done a course on the subject, wouldn't be able to answer any questions on what might go wrong. If they had only been slightly exposed to the technical subject then their replies to such technical interview questions would probably be very limited.
But if you had genuine and extensive experience of a technical area, then you could probably give a lengthy answer about the possible problems and their solutions.
From an interviewer's point of view, someone who knows what can go wrong demonstrates knowledge more effectively than giving someone a technical test. Knowing what can go wrong and the ways of avoiding it is the way to produce a successful outcome to any technical task.
So if your interviewer does not ask technical interview questions like that, you should aim to turn the interview round so that you are able to bring out your knowledge of the particular technical area or skill that they need to know about.
Before you go to the interview, think about all the things that may go wrong in this area or when applying this particular skill. Also think about how you have solved these problems to make them right.
So, when you go to the interview, be determined to get this across; that you know what the issues are and how you can solve them. Don't just passively sit there and answer the questions they ask. It should be quite straightforward to bring up the topic of the problems that occur and the solutions you have come up with.
If it doesn't come out readily during the interview, when they ask if you have any questions you should immediately ask them about the main problems that they have had at their site, and then discuss how they are solving them. You can then go on to talk about similar problems that you have had and what you have done to correct them. If they haven't come across some of these issues yet, they might be very keen to have you on board for when they do.
But even if they have come across the problems, by bringing them up you will show your understanding of the subject and that you are able to sort out problems that can occur.
If you are an interview candidate, make sure that you have prepared a list of technical interview questions about what can go wrong and prepare some statements about how you would put it right; go to the interview determined that you are going to make this point.
