Skills Level Required
How much skill level is required for the given job? There are variable levels of experience and skills needed for each job. While some will not be requiring much effort, others will require you to bring all your skills to work.
You must see if you are comfortable with the level of work you will need to perform and whether you have the right set of skills or not.
How much time will you need to put in each day? It is an important question to ask while you evaluate the job. Even if the level of skill required is not all that great but the job needs you to work for long hours, you must carefully consider it. If you are already doing a job or have been doing other such jobs at the same time, will you be able to perform all the tasks well at the same time or not.
Once you know that you have the right skills and have the time for the job as well. The next thing that you need to know is that how much money is being offered. In most cases, it is quite reasonable but there are jobs that require a lot of hard work and yet do not pay well enough. Make sure that you get paid well for your good work.
Other Similar Options
Do compare the job at hand with other similar jobs that are available in the market as well as the ones you have previously done. See if the offer is good enough and makes sense or is it over burdening for the kind of compensation you will receive. This is an important factor to keep in mind before you make the final call.
