In your opinion should I accept this internship offer? Give your honest opinion guys.

So as you all know I just completed my MBA very recently and job searching since I quit the edtech internship. Its been very hard honestly due to the competition here in Bangalore in India even though its the IT hub as I did MBA in Business Analytics and marketing and honestly its very hard to get Analytics roles as a fresher. So today I had an interview which was virtual today but it was a Data Entry intern role in this startup Arnifi. The job description said it required good Analytical skills and Microsoft Excel skills so I applied. So had the interview but the interviewer asked if I did an MBA in Business Analytics and an internship too in it before why am I looking for a Data Entry role. I said to gain sufficient analytical and excel skills but he said there is no analytics in this role and it will just be a basic copy pasting of data on MS Excel. The office is also in Kadubeesanahalli area which is the IT corridor of our city Bangalore but yeah the role just has copy pasting data which feels like a downgrade compared to what I learned in my MBA. A proper Data Analytics role requires Power BI, Python or SQL but here I won't gain these skills. The pay/stipend is 15,000 rupees per month(about $156.69 per month) during the internship period and then it will convert to full time based on how I perform in the internship and they can also fire me anytime without a notice if my performance isn't good as I am an intern. But I am worried whether this will have a future as its just basic Data Entry which anyone even a high school graduate with some Excel knowledge can do and I am literally done with an MBA. I definitely need a job tho for real now at 25.

Also another thing is they want me to join immediately. In the Job Description, they said we can join within 5-6 days of the offer so I asked whether I can join Monday but they are saying they can't wait till then and want immediately by tomorrow or Thursday. I hesitated to say no and they confirmed in the offer letter that I will be joining on Thursday( 14th May). Also they want me to fully confirm and sign the offer letter and send it by today itself. I am not getting a time to think a bit and send it tomorrow. They are continuously messaging me on Whatsapp and calling saying when will I sign the offer letter and send it to them and confirm it so I guess they urgently need to fill this position and there is probably high turnover here. They are repeatedly messaging about it but I wanna revert about it tomorrow. What should I do? Should I confirm it and join it even if its a Data Entry role and not fully aligned with my MBA? Give your honest opinion guys.
