Can I get a job in PR and advertising after doing a bachelor’s in journalism?

Without a doubt!

Examine the similarities between the three professions of public relations, advertising, and journalism. All three demand the capacity to convey stories in a unique way. Because of time and financial restrictions, advertising is the most difficult of them.
However, public relations and journalism are inextricably linked. You work for the firm as a Corporate Journalist in PR. The job is the same, but the role is different.

Traditional journalism, on the other hand, offers more diversity but pays less. Advertising is the most diverse and creative of the three, but it is also the hardest to break into.
