- '>=7': This category indicates that the person has been employed for more than or equal to 7 years. It is likely that individuals with stable long-term employment are more likely to receive credit.
- '1<=X<4': This category represents employment duration between 1 and 4 years. It is possible that individuals with a moderate duration of employment may have a higher chance of receiving credit.
- '4<=X<7': This category signifies employment duration between 4 and 7 years. Similar to the previous category, individuals with a moderate duration of employment may have a higher chance of receiving credit.
- 'unemployed': This category indicates that the person is currently unemployed. It is possible that individuals who are currently unemployed may have a harder time getting credit.
- '<1': This category represents employment duration less than 1 year. Individuals with short-term employment may face difficulties in obtaining credit.
