I am 3rd year chemical engineering senior and I feel like I know nothing absolutely nothing! I hate this major.. is it waste of time if I started civil engineering from 0 which means 5 another year from now ? I am 20 years old and I feel passionate about this major #doctor #engineer #professional #chemical #civil #advisor
Since you are already a senior, I would not change majors at this point simply because MANY people do not work in the field they graduated into. Not liking what you are studying has little to do with what you will do once you graduate. A degree only gets you in the door – it creates an opportunity to be hired. There are a lot of fun jobs out there for chemical engineers and probably many you have not considered as potential career paths. For example, Procter & Gamble hires a lot of chemical engineers and while, yes there are the typical formula design jobs, there are also jobs that design methods to analyze the effects of formulations to see if there are marketable benefits. Chemical engineers may end up working as simulation engineers who model the theoretical effects of products or even as statisticians who correlate the results from quantitative methods to consumer test results. A learning I have had is what you study is MUCH narrower than what you can work on with the degree, but you don’t know this until after you graduate. Also, be sure that you are not asking this question because you are afraid to graduate and make the transition - never make a decision out of fear. As far as "know nothing absolutely nothing" that's okay. Entry level positions for college grads do not expect you to know anything. They expect you to be able to follow instructions and carry out the work delegated to you by more experienced professionals. It may help to adjust your expectations of your degree - the process of getting a degree teaches you how to think. It is not a process of becoming an expert at anything; becoming an expert is the purpose of experience. The purpose of the degree is to create an opportunity you probably would not have had without it.
I would recommend not changing majors at this time and to attain your degree. Many of the subjects you took should be applicable to all types of engineering. Many jobs you take will lead you to areas completely outside your major area.
Several areas of civil engineering would be very relevant to your chemical engineering degree such as water quality analysis and management, waste water treatment, various types of materials found in geotechnical analysis, water and wastewater plant design as examples.
I would recommend pursuing a job with a large engineering firm that does work in many areas and then you can build your career in an area that interests you.
