I am new to Upwork. I have created my profile and updated my skill sets along with the portfolios. I am finding jobs related to my skillsets and submitting proposals, but I am not getting hired. kindly guide me on this.
Submitting proposals doesn't always guarantee that you will get hired or get a chance to be interviewed, but you shouldn't give up on sending proposals to potential clients.

When you apply for jobs, make sure your proposal is well written and that you're absolutely qualified and certain of your ability to complete the job you're applying for.
