There is only one interview stage involve for this position. Typically for contract term up to 2 years. I believe interview process is not really tough. Depending on the panel as well. During my time, I've been interviewed by Inspection Engineer. Although job description for the role posted on LinkedIn is quite easy for me to nail down but then it is way beyond my expectation. It seems that interviewer already had his desired candidate behind his back prior to my session. So, what he did just trying to kill off my application by throwing every single little question which is only available in API standard and code.
