Got a sales offer. What should I do?

For a lil background I am a final year BE student from CSE. Currently interning at an AI start-up.

I forgot that I had applied to this company n just attended the interview for the sake of it. N boom.. i crack the interview with ease. It is an ed-tech company which is pretty established. And the CTC is quite good(7-8LPA) considering it is being offered to freshers.

I have made up my mind to decline the offer (ignore) cuz I want to stay in tech and have heard that jumping from sales to tech is difficult.

I wanna see what ppl in the industry think.. sooo yeah I'm all ears listening to opinions...
