If you're looking for a job in Nigeria you can go to job posting websites or job search websites for jobs in Nigeria such as
https://www.hotnigerianjobs.com/ or
https://ngcareers.com/jobs/2
There are many other job search websites so I would recommend going to google and search for Jobs In Nigeria and some job posting and job search websites for jobs in Nigeria should come up in the google search.
If you do get an interview for the job make sure you show up on time and are ready for some answers to the questions that the interviewer may ask.
Also if the job hasn't called you back after writing the resume then it's a good idea to contact the job and let them know you're very interested in the job.
