Have you any experience, what is accounts, what is the entry of cash purchases, type of record keeping, ledger means, what is the role of ledger in accounts.

I went to 3 round interviews (3rd one was also the last one). Interviews were not too difficult and was mostly a discussion about my work experiences and background. The whole process took more than 3 months. However I never received an answer. I tried to follow up for a few weeks (about 2 months), but unfortunately the HR did not provide me any additional information. I assume all of this happened because of the situation with Covid-19. However the lack of follow up looks really unprofessional.
