Still having trouble landing that new job or leaving a lasting impression with an interviewer? LinkedIn Career Expert Andrew McCaskill sits down with Brad Smith to outline the biggest mistakes job applicants are making when interviewing for a role, from simply showing up late or not being prepared.

"A lot of the old school things really, really matter. The other thing that you've got to think about too is that level of enthusiasm, you can't discount it. Every point that you have to engage with a recruiter or a hiring manager, you need to be telling them, 'here's why I am right for this job because I want to have an impact at your company in this role,' McCatskill tells Yahoo Finance. "People are also not sending the 'thank you' note. The thank you note is not really about thanking them for their time, I mean it is, but it's really about you putting one last salvo out there saying I want this job."

McCaskill underlines the importance of networking to better understand the industry you are interviewing in, as well as building up necessary skills.

"If you know that there are skills that are needed for work in that particular industry that you need to bone up on, do some micro learning, things like LinkedIn Learning or online courses or certifications to help you start to one. Speak the language of that industry and of those occupations, that will save you in so many ways," he says.
