Interviewer was cool, but the fact that they want us to jump right into code without thinking of a logic, or even a review of the logic along with the fact that we get only 1 hour (on zoom) for all the above wasn't helpful.
Questions are conveyed orally which isn't good for anyone as there will be some communication gap especially on a remote call.
I would say anyone who knows logics available from online interview prepare websites will be able to crack.
But frankly I don't see how recruiter will be benefited with this alone. All the best
