Yes, with caution. Star or dot ratings visually communicate relative proficiency and are common in creative and tech CVs. Be precise and honest: if you rate yourself 5 stars in a skill, be prepared to defend that in an interview. Avoid self-rating at maximum for every skill, which looks implausible.
In tech and creative fields, a well-chosen interests section can be a conversation starter and signal personality fit. Keep it to 3 to 5 specific items: open source contributor, hackathon organizer, documentary filmmaker. Avoid generic entries like reading and travel which add nothing.
Use this format when applying to creative tech companies, digital agencies, marketing departments, design studios, or any role where your personality and aesthetic judgment are part of your value. For ATS-heavy corporate environments, large enterprises, law, finance, or government, use a clean single-column version. It helps to have both ready.
Usually one page. Freelance CVs should be ultra-concise: your strongest clients, your best outcomes, and your most relevant skills. Hiring managers and potential clients do not have time for exhaustive project lists. The link to your portfolio does the heavy lifting.
A working, current URL at the top: portfolio, GitHub, Dribbble, or all three. For tech professionals, a GitHub profile with active, quality commits is often reviewed before an interview is even scheduled. For designers, a portfolio that loads fast and shows relevant work is essential.
