Knovva Academy interview questions

Phone screen interview for 30 minutes with HR and an engineer manager. Introduction of Knovva Academic, responsibilities of the position, and basic JavaScript questions. Then, the hr will contact candidates whether they are accepted or not.

Received interview request via email, met with a few ppl including HR, CEO and ppl from other dept who can't well explain their positions. Had to go there for 2nd time because one person at the 1st time interview cancelled at last minute. After twice interview no word at all from HR, even though sent a follow up email. Overall the entire experience was unprofessional. Many questions they asked were meaningless, I wonder they truly have this position opening.
