In my country, most of the work now is in the construction sector, so companies mostly require architects, civil engineers, mechanical engineers, and electrical engineers. On the other hand, the oil sector also exists, but it is difficult to access and requires high experience to work in it. So, for a chemical engineer, it is very difficult to find work in the specialty. Likewise, there is the pharmaceutical manufacturing sector, but like the oil sector, it is difficult to work in it. So, as for your advice to work in a related sector, should I work in HVAC systems, or is it considered a specialty only for mechanical engineers? Also, are there other job ideas?
