Hey Aarti,
A Professional LOR talks about your work ethic and performance as an employee.

This letter is usually given by your team leader, manager, senior manager, and if it’s a startup, your CEO. Do note that if you are an entrepreneur, your Professional LOR would come from a mentor or your co-founder.

Here, you can highlight the kind of projects you’ve worked on, any awards you’ve won, the CSR initiatives you participated in, or any other achievements from your workplace.

It would be a good way to showcase how you would qualify as a professional – an important factor when it comes to applying for internships and jobs when you’re studying abroad.
