Typically, engineers will have deep knowledge in one area and basic knowledge in related areas. For example, mechanical engineering curricula typically include introductory courses in electrical engineering, computer science, materials science, metallurgy, mathematics, and software engineering. [67] => [68] => An engineer may either be hired for a firm that requires engineers on a continuous basis, or may belong to an engineering firm that provides [[engineering consulting]] services to other firms. [69] => [70] => When developing a product, engineers typically work in interdisciplinary teams. For example, when building robots an engineering team will typically have at least three types of engineers. A mechanical engineer would design the body and actuators. An electrical engineer would design the power systems, sensors, electronics, embedded software in electronics, and control circuitry. Finally, a software engineer would develop the software that makes the robot behave properly. Engineers that aspire to management engage in further study in business administration, project management and organizational or business psychology.

After seven years of working after graduation, two years of responsibility for significant engineering work, continuous professional development, some highly qualified PEs are able to become International Professional Engineers Int(PE). These engineers must meet the highest level of professional competencies and this is a peer-reviewed process. Once the IntPE title is awarded, the engineer can gain easier admission to national registers of a number of members jurisdictions for international practice.{{Cite web |title=NCEES International Registry for Professional Engineers |url=https://ncees.org/records/international-registry/ |access-date=2020-02-08 |website=NCEES |language=en-US}} [185] => [186] => In Canada, engineering is a self-regulated profession. The profession in each province is governed by its own engineering association. For instance, in the Province of British Columbia an engineering graduate with four or more years of post graduate experience in an engineering-related field and passing exams in ethics and law will need to be registered by the Association for Professional Engineers and Geoscientists ([[APEGBC]]){{Cite web |title=Engineers and Geoscientists BC |url=https://www.egbc.ca/ |access-date=2018-09-11 |website=egbc.ca |language=en-US}} in order to become a Professional Engineer and be granted the professional designation of P.Eng allowing one to practice engineering. [187] => [188] => In [[Continental Europe]], Latin America, Turkey, and elsewhere the title is limited by law to people with an engineering degree and the use of the title by others is illegal. In Italy, the title is limited to people who hold an engineering degree, have passed a professional qualification examination (''Esame di Stato'') and are enrolled in the register of the local branch of National Associations of Engineers (a public body). In Portugal, professional engineer titles and accredited engineering degrees are regulated and certified by the ''[[Ordem dos Engenheiros]]''. In the Czech Republic, the title "engineer" (Ing.) is given to people with a (master's) degree in chemistry, technology or economics for historical and traditional reasons. In Greece, the academic title of "Diploma Engineer" is awarded after completion of the five-year engineering study course and the title of "Certified Engineer" is awarded after completion of the four-year course of engineering studies at a Technological Educational Institute (TEI).

[194] => [195] => === Asia and Africa === [196] => In the [[Indian subcontinent]], Russia, Middle East, Africa, and China, engineering is one of the most sought-after undergraduate courses, for which entrance examinations are highly competitive. [197] => [198] => In Egypt, the educational system makes engineering the second-most respected profession in the country (after medicine); engineering colleges at [[Egyptian universities]] require extremely high marks on the General Certificate of Secondary Education ({{lang-ar|الثانوية العامة}} ''al-Thānawiyyah al-`Āmmah'') – in the order of 97 or 98 per cent – and are thus considered (along with the colleges of medicine, natural science, and pharmacy) to be among the "pinnacle colleges" ({{lang|ar|كليات القمة}} ''kullīyāt al-qimmah'').{{Citation needed |date=March 2024}} [199] => [200] => In the Philippines and [[Overseas Filipino|Filipino communities overseas]], engineers who are either Filipino or not, especially those who also profess other jobs at the same time, are addressed and introduced as ''Engineer'', rather than ''Sir/Madam'' in speech or ''Mr./Mrs./Ms.'' (''G./Gng./Bb.'' in Filipino) before surnames. That word is used either in itself or before the given name or surname.

Holding the requisite qualification does not afford automatic entitlement. The title has to be applied for (and the appropriate fee paid). The holder is entitled to use the title in their passport.

Anyone misusing this title in France can be fined a large sum and jailed, as it is usually reserved for graduates of French engineering ''[[grandes écoles]]''. Engineering schools which were created during the French revolution have a special reputation among the French people, as they helped to make the transition from a mostly agricultural country of late 18th century to the industrially developed France of the 19th century. A great part of 19th-century France's economic wealth and industrial prowess was created by engineers that have graduated from [[École Centrale Paris]], [[Mines Paris - PSL|École des Mines de Paris]], [[École polytechnique]] or [[Télécom Paris]]. This was also the case after WWII when France had to be rebuilt. Before the "réforme [[René Haby]]" in the 1970s, it was very difficult to be admitted to such schools, and the French {{lang|fr|ingénieurs}} were commonly perceived as the nation's élite. However, after the Haby reform and a series of further reforms ([[Modernization plans of French universities]]), several engineering schools were created which can be accessed with relatively lower competition. [212] => [213] => Engineering positions in France are now shared between the {{lang|fr|ingénieurs diplomés}} graduating from engineering {{lang|fr|grandes écoles}} and the holders of a [[master's degree]] in science from [[List of public universities in France|public universities]].
