Are optional cover letters really optional?
It depends on the company and the job you are applying for. Some companies may require a cover letter as part of the application process, while others may not. It is best to check the job listing or the company's website to see if a cover letter is required. If one is not required, it is still a good idea to submit one as it can help you stand out from other applicants and provide additional information about your qualifications and interest in the position.
