How common is it for development job applicants to lie about their skillsets and experience?

Had an applicant come interview for a senior software engineer role, has been in the same company for 8 years and his resume is sprayed with almost every tech speciality and language there is, claims to be proficient in 8+ languages, done AWS server migrations, built CI/CD pipelines from scratch, written CloudFormation scripts, built microservices, worked with AWS services and serverless platforms, has managed a team, does salary and performance reviews

My gut feeling is when someone claims to have knowledge and experience across multiple specialities, they’re skills in any of those domains are only skin deep
