Chemical engineering is an exciting career choice and one in which qualified candidates are in high demand. The role of a chemical engineer involves taking materials and designing processes to change certain properties to give them another purpose. A wide range of industries relies on chemical engineers to produce new materials so a role in the sector can lead to many different opportunities. Production using chemical engineering is right at the forefront of human development. In this multibillion-pound industry candidates will work in fast paced environments solving problems on a daily basis whether you are in a production environment or working behind the scenes in R & D.

leadership and supervision then expect to be asked questions on competencies such as people management and motivation.
How Should You Prepare For Your Engineering Interview? Before you get started interview preparation is vital. Prepare by analysing the Job Description, Job Advert and Person Specification to gain an understanding of the aspects of chemical engineering covered in the role. Your next step should be to consider the types of behavioural question you could be asked for each aspect of the role. In competency based interviews past performance is the greatest tool for predicting future results so questions will be focussed along the lines of “Tell us about a time you have…..”. For each aspect of chemical engineering you have identified, it is worth preparing examples of when you have delivered relevant behaviours. The best method for answering competency questions would be using the STAR model. With the STAR model, you would state first the Situation to provide context, describe the Task , which needed to be undertaken in order to progress, outline the Actions you took and finish off by tangibly describing the Results. Tip – Tip – Sometimes Sometimes you can demonstrate your knowledge of a technical question by providing a competency-based answer.
