Hannah Williams only started working full-time three years ago, but she still has an extensive resume.

She has held five jobs in the last year, with the longest being a full year.

There were a number of reasons why she left those jobs. She discovered that the job she signed up for was different. Sometimes it was due to poor work-life balance.

This was during the Great Resignation, so I felt like I was in control, because other people are quitting as well. She told CNBC Make It that she could do it again.

She is not alone.

According to the research done by LinkedIn, users who changed their jobs increased in 2021. The report showed that Generation Z workers were the most restless.

25% of respondents say they hope to leave their current employers in the next six months.

Gen Z workers would spend an average of two years and three months in a job, while the younger generation would stay for 6 months more, according to a research by CareerBuilder.

It sends quite a few negative signals … It tells me that if the going gets tough, you get going.

Gen X employees spend an average of 5 years in the same job, while Baby Boomers stay in their jobs for about 8 years.

The days of working for the same company from start to finish may be over, but what do hiring managers think about job-hoppers? CNBC finds out.

It's more acceptable than ever, but it's still too quick to switch jobs under a year of tenure, according to the chief people officer of Relay Payments.

It sends a lot of negative signals. You lack commitment. You lack perseverance. If the going gets tough, you get going.

The so-called "sweet spot" for changing jobs is every two to three years, as it allows job candidates to make a commitment and honor it.

If a tenure lasts between three to five years, it will be wonderful, said the Managing Director for Singapore and Malaysia.

How long should you work? Experts say two to three years is the optimal time.

One of my favorite questions to ask is what the company's calendar year is. I want to know if you went through two budgeting cycles at the company.

At the start of a calendar year, companies will usually budget for new initiatives, which will provide new opportunities for employees.

Those who see the company start projects and initiatives should be given key performance indicators for the full year, said Dass.

Williams faced questions from potential employers during her interviews.

It costs money to hire people so they are always worried that I will start and then leave and screw them over. They are worried about me wasting their time.

Williams insists that her goal is not the goal at all, but her work ethic. She told CNBC Make It that she gets deep into the weeds as soon as she starts.

People will say that you didn't learn anything in two months. I work eight hours a day, five days a week, what do you think I have been doing?

agility and adapting to new environments quickly are possible upsides of job-hopping every two years or so, according to industry experts. They stress the importance ofdepth of thinking, which comes with a longer tenure.

Hannah Williams, who tripled her pay in two years through job hopping, said that the salaries that people are making out of college are not realistic anymore.

It's very different to know it once and 10 times. It is not related to your level of intelligence. It is just a degree of internalization. She said she would take the achievements on a job-hopper's resume with a pinch of salt.

She said that the younger generation is not wrong in saying that they have mastered the job.

Team members, bosses and even the wider organization are factors of change.

It will catch up. It will affect your depth of knowledge and ultimately, your value to future companies... The short-term gain isn’t worth the long-term risk.

Job-hopping may be a quick way to raise one's pay compared to promotions within the same company. Hannah was paid less when she was in her first job, but now she is paid more as a senior data analyst.

He warned against the price that will have to be paid in the long term.

It will catch up. Your value to future companies will be affected by it. She said that you will not be as competitive as your peers.

The short-term gain is not worth the long-term risk.

She would recommend job-hopping to anyone.

The job market is hot. She said that people are hiring, they are paying well, and they are giving good benefits.

If I keep doing this for 10 years, that would be bad. She said she would wreck her resume.

I have a track record, so I would have to explain why I left five times in a short time.

If there are no employment gaps, recruiters may see the job-hopping as a good thing.

She said that if someone is getting asked somewhere else for better money and a better position, it is human nature to move.

If there are big gaps, it means that this person has a pattern of leaving when the going gets tough.

When it comes to toxic workplace culture, she wouldn't fault a potential employee for leaving quickly.

I want to know if you signed up in good faith to work for a company that you believed in.

It could raise serious red flags for employers if it happens too often.

If it only happened once or twice, I will give you the benefit of the doubt and I will have a conversation. She said that once you become a serial job-hopper, it will tarnish your reputation and it will be hard to recover.

To minimize the need for job-hop, Zimmerman advised employees to find the right place for themselves.

If you are ambitious and want to keep up with your growth pace, you should pick a company that is on a wide growth trajectory.

Job hopping can only last for so long, so I always recommend for job seekers to first decide what they want. You get tired of moving around after a while.

She hopes professionals can use job-hopping to do self-reflection and self-discovery so that they can eventually settle in a job where they can stay for anywhere between two to five years.

A lot of times, professionals don't know what they want to do in the future.

Take the time to write down a list of what you need from a job in order to be happy and stay there.
