Precision is calculated as TP / (TP + FP) where TP is true positives and FP is false positives.
Recall is calculated as TP / (TP + FN) where FN is false negatives.

Interview Preparation Tips
On the starting date you'll again message one person(Yashima Kamra) on Skype, they'll give you 'Zulip'(it's an open source chat system, interface is kind of like Discord but too basic) access. Now you need to message in an assigned group in Zulip. The Zulip part is 'Training' in real but good luck getting any support from the other person. He/she will just give you commands, and if you ask any questions or ask for assistance to understand the new process they'll simply ignore that.
Then if you're lucky like me one day they'll report that you're ate fault, you haven't reported so they've revoked your Zulip access.
I have joined there or you can say hoped to work atleast(as it was 4 hours/day job) but that's not possible it seems.
If you're looking for jobs here I'd suggest to give it a try ofcourse so that people can actually know about this company's rubbish people.
