Preparing for current affairs for an interview is crucial to showcase your knowledge and awareness of the world around you. Here is a guide on how many years of current affairs you should focus on:

- The most important current affairs to focus on are the recent ones, typically ranging from the past 6 months to 1 year.
- This includes significant events, developments, policies, and decisions that have taken place recently.

- It is also beneficial to be familiar with medium-term current affairs, which span from 1 to 3 years.
- This helps in understanding the context and background of ongoing issues and trends.

- While the focus should primarily be on recent and medium-term current affairs, having a general understanding of long-term issues is also important.
- This includes historical events, global trends, and persistent challenges that continue to shape the world.

- Depending on the specific role or industry you are interviewing for, it may be necessary to delve deeper into certain specialized areas of current affairs.
- This could include sector-specific developments, policy changes, or emerging trends within your field.
In conclusion, while the primary focus should be on recent and medium-term current affairs, it is essential to have a broad understanding of long-term issues and specialized knowledge relevant to your interview.
