I think, what's important is also for you to ask yourself if you have a better plan B at this point.
Ask yourself some of the questions below:
1. Are you from an industry that's adversely impacted and would in all probability not recover even in the next 6 months?
2. Are you in a job that currently is as at a high risk? If you do defer the program, would you have a credible and fulfilling job for the next 1 year?
3. Do you think your profile is solid enough to make it through and get hired in case this was a 1 yr program without internship? Or were you planning to transition into another role/industry?
If the answer to your 3rd is that you are positive you would have got a job, I would say go for it. If you have talked to a few students, you would also know that almost 60% students get a job through the final recruitment cycle in second year rather than a PPO from internship.
