There are several reasons why Nigerian graduates find it difficult to get jobs, including:

1. High Unemployment Rate: Nigeria has a high unemployment rate, and this has made it difficult for graduates to secure jobs. According to the National Bureau of Statistics, the unemployment rate in Nigeria is 33.3% as of the fourth quarter of 2020.
2. Limited Job Opportunities: The job market in Nigeria is highly competitive, and there are limited job opportunities available for graduates. The number of graduates exceeds the number of available jobs, making it challenging for graduates to secure employment.
3. Poor Education Quality: The quality of education in Nigeria is generally poor, and this has affected the employability of graduates. Many graduates lack the necessary skills and knowledge required by employers, making them less competitive in the job market.
4. Lack of Practical Skills: Many Nigerian graduates lack practical skills, and this makes them less attractive to employers. Practical skills such as problem-solving, critical thinking, and teamwork are essential in the workplace, and graduates who lack these skills may find it challenging to secure employment.
5. Nepotism: Nepotism is prevalent in Nigeria, and it has made it difficult for graduates to secure jobs based on merit. Many employers prefer to hire individuals based on their connections rather than their qualifications, making it difficult for graduates to compete.
6. Inadequate Government Policies: The Nigerian government has not implemented adequate policies to address the high unemployment rate in the country. There are no incentives for businesses to create jobs, and this has contributed to the limited job opportunities available for graduates.

In conclusion, the reasons why Nigerian graduates find it difficult to secure employment are complex and multifaceted. Addressing the issue will require a concerted effort from the government, employers, and educational institutions to improve the quality of education, provide practical skills, create more job opportunities, and implement policies to address the high unemployment rate in the country.
