The Steps To Take Before Landing A Job

You probably need to take the following steps as follows before landing a job.

Firstly, you can read an job advertisement on an hiring website or in a newspaper. Secondly, you should apply to the job by sending your resume and cover letter when *you find finding out an interesting job. Thirdly, you need to go for an interview. Finally, you will receive and accept a job offer.

You will start **[to work] after ***[doing] these steps.

*when adressing the "you," stick with it! (don't use a participle here)

"to find out" is a phrase in English but it means something different 

**correct, but awkward.  An English speaker would say "you will start working" 

***"completing" is more idiomatic here
