Basically everyone dreams of that 'work from home' kind of job but in reality, it is difficult but it depends on what kind of work you are expecting from 'home office'. There are tonnes of freelancers websites where clients go to and post job offers and you get the chance to apply and send proposals. These websites do charge a fee (at least 20% from the what you will earn). These jobs vary from translation to web-designing to engineering sketches etc.

The company I used to work for (software engineering company) did offer one of its workers the chance to work at home, which is home office, because he mainly does programming and coding. So he brings the company's laptop to a different city, which is 7 hours away and he would be at the company every 2 weeks, depending on what discussion needed to be done with the bosses.

Non technical work from home jobs = creative design (web, print, video) or writing (proposals, resumes, LinkedIn profiles, translation)

If you have a bit more technical background, your writing options expand a bit more eg. engineering/development manuals/translations, legal, business, regulatory stuff.

Go to Upwork and do your homework. You'll be competing for jobs globally, against people from around the world. If you're good you can survive, or it could be a supplemental income only. Why limit yourself to Malaysia....

oversea website, i did it before, but its freelance, if it, coding and etc very damn easy to get, payment is good because in USD. try to find international one, they paid by paypal

I would say stop limiting your job search to "work from home". Even small companies nowadays (startup) can offer you such flexibility if you're not required to be in the office to do your work.

My first official job was doing an in-house marketing/branding for a Singaporean company based in PJ handling 7 countries (APAC). I was working regular office hours until my local marketing manager left and I had to report directly to Singapore which invalidate the needs for me to be in the office everyday.(travel to office and overseas once or twice a month for meetings)

4 years later (earlier this year) I accepted a new job offer doing Corp Comms and Awareness for an international bank with the thoughts of working in an office environment again. Turns out my whole team was working from home as well. I got lucky again. (only in the office for weekly meeting etc)
So yes you usually can work from home in a regional kinda job where maybe your boss will be in Singapore or some other countries and you are working with those other countries most of the time.

how they know if you don't really work at home? like playing PS4 during office hour?
