I think this is still very narrow minded around why big tech or any large company needs so many people. Not that I know everything, but to expand and to keep in mind none of these areas are actually developing or providing the service your business might be known for. Accounting, large accounting teams are required to manage the various accounting requirements and technicalities required of organisations that are large or have large enough revenue streams that require them to be financially audited by a third party auditor. These teams perform the accounting function of the company but also support the financial audit process required. Of which there is an enormous amount of regulation by governments around the level of internal control of the organisation (see governance, risk and compliance) Governance, risk and compliance, when you become large enough you need to start managing your risk and defining your appetite for risk as company. This is how your board and audit committees who are charged with governance understand how the organisation is managing its risk. Every company of large enough size has to manage risks relating to cyber security, IT, legal, employee retention, product delivery, sales etc etc. Each of these risks needs to be assessed and various GRC departments jobs are to ensure that the organisation maintains an effectively controlled environment to manage its risk in line with its appetite. Balancing the cost of business and the cost of compliance. Large enough companies are required to maintain three lines of defence, which also means you are subject to various external audits. Legal departments, are required once you reach a large enough size to combat the various legal threats you may incur when delivering a product or service. Either legal threats introduced by compliance, breaches or brought on by individuals. Marketing & Communications, you've made a product, you have/want a brand or you're providing a service. This team actively manages this brand, helps build it and markets it to the outside world. They can often also be responsible for clearing, defining and/or managing the internal and external communications that go out on behalf of the organisation. Which is crucial for managing legal risk and maintaining brand. Human resources, required to manage the people within an organisation of such a large scale. This may include talent acquisition and retention into graduate roles and or senior positions. When there are so many people you can no longer manage yourselves nor be able to identify what people's need are nor begin address them. Payroll, who pays you? Internal IT/Cyber, need I say more? Multiply these areas across multiple geographies or jurisdictions in which you operate. You can start to appreciate why companies have so many people.
