Hi, I am a mechanical engineer who has worked only in start-ups, for past 3 years. Main experience is Mechanical design CAD with bit of FEA. Problem is I want to move to a more traditional company. I had had an interview with one of the largest oil and gas company for role of design engineer in safety valves. Sadly I couldn't relate to their requirements of product lifecycle GD&T FMEA etc. How do I fill these gaps. Thought of doing courses but cumulatively can't afford all courses. There are free links for GD&T though. Are there other skills I need to have. CAD experience is more hands-on but I feel I m not doing it the way most professionals do. I keep learning new functions everyday. Is there a way to learn or relearn above skills in more structured way, similar to how a graduate would have learned in top companies with graduate jobs and training.
