You're looking for a new job, so it's time to update the ol' resume. But when you try to describe your last position, you stare off into space thinking, "Wait, what did I do, exactly?" Well, who's better at describing the duties of your role than the employer itself?

If you want to secure a decent wage and steady employment, it helps to have a job that's in very high demand. According to the latest Hays Jobs Report, skills relating to finance and information technology are good for your resume in 2018. Here are the top 30 jobs that employers are currently trying to fill.

Dear Lifehacker, I've recently relocated to London for a year or two and am looking to start work. Most of my applications have been via recruiters who have responded with a range of roles. I'm interviewing for a couple of jobs this week but one is about 90 minutes away in another city and the other sounds like good work but the organisation might not be the right cultural fit for me.

Looking for a job is difficult under the best of circumstances, and it gets considerably more so when you aren't prepared. Optimistically, we stick with a gig for a while even if we don't love it, neglecting to keep our resumes and other materials prepped if an opportunity comes up that we want to jump at.

There's no shortage of resume tips on the internet, but word selection is one area that's often overlooked. Believe it or not, your verb choices can have a serious impact on how your resume is received by prospective hirers - even if the listed skills and achievements remain otherwise unchanged.

This infographic from Eapplicants lists 22 action verbs that have been proven to strengthen resumes, along with a multitude of extra tips.

Just as companies have to weed out the good candidates from the bad, you need to be able to tell the good companies and positions from the ones that will just waste your time. Here are some red flags in job descriptions and interviews that can warn you about a potentially terrible job.

Job hunting is always an exercise in patience and managed expectations. Whether you're looking for a new gig, trying to get your foot in the door of an unfamiliar industry, or just want to ensure your professional life stays up to date and appealing, there's no doubt you'll have to get on LinkedIn and spruce up that profile. Let's be honest: Your current profile probably isn't cutting it, and needs some work if you want to make a good first impression before you meet face-to-face for an interview.

Dear Lifehacker, I'm thinking of moving on from my current job, but there's a problem. I have some health issues that require a weekly appointment and I currently have my appointment on a Friday afternoon. My current manager has rearranged my work hours slightly so that I can attend this appointment. My question is: if I get an interview for a new job, should I tell them about this at the interview? If so, how do I go about it?

Let's not sugarcoat it: Searching for a job can be awful. It's a little like apartment hunting. Or partner hunting. You have to sift through a lot of unattractive options for one gem in the rough. But there are much better, more effective and sanity-saving ways to find appealing jobs that don't involve refreshing Seek or CareerOne.

Job searches are already a complicated stress-maze of multiple sites, searches and alerts, so you might think it's bad news that you also need to expand your search to social media. But actually, Twitter and Facebook can be a relatively (relatively) pleasant part of the job search process.

Nobody is immune to layoffs. Whether you're an executive or an entry-level hire, layoffs can - and probably will - affect you at some point in your career. Consultants and freelancers have a bit of a buffer thanks to their multiple income streams, but when their industry suffers, they suffer too. (There's nothing like losing four clients in a single month.)

Dear Lifehacker, I have recently moved interstate and started a new job. What's your best tip for getting myself known to the people that matter while still maintaining a good relationship with my peers and staff? I don't want to be a brown nose but I have come from a well-respected position - I knew the movers-and-shakers both within my organisation and without and I want to get back to that point as quickly as possible.

LinkedIn has revealed the 25 most desirable employers in Australia. The rankings are based on the online behaviour of 8 million job seekers and professionals who make up LinkedIn's Australian user base. Here's the full list - with links to available jobs.

We've all had the experience of applying for a job online - you submit your resume and cover letter into the dark abyss of some online hiring portal and, aside from an auto-generated "Thanks for applying!" email, you never hear another peep from the employer.

Dear Lifehacker, Much of your advice around resumes is all about getting your foot in the door -- past the auto-screeners and the six-second glances. But what if I'm already in the door? I'm being referred for a job, and I'm wondering if you've got any advice for this situation. I figure they'll spend a bit longer looking at it since they're giving me an interview.

You got the job! Oh, but you don't want or need it any more. What do you do? What should you say?

So you didn't get the job -- bummer. It stings but the process isn't over yet. Before you move on to the next potential gig, do these three things.

A one-on-one job interview is stressful enough. Add three to five other people all sitting across from you and firing questions your way and you have some people's worst nightmare. It's no one's idea of a good time, but with a little preparation and practice, you come across as a confident, excellent candidate despite the intimidating format.

It's pretty common for interviewers to ask you to share about specific experiences or skills related to the job you're interviewing for, but if you haven't been in the exact situation or used the tool they mention, you can get tripped up. Here's what to say so that you can come across as a good candidate even if you don't have an answer that matches their specific question.
