I had 2 phone interviews. I Was rejected due to lack of JS knowledge. I think it was fair. To be honest, I have facebook and Google interviews coming up and my preparation is more focused on my algorithm skills than my JS skills. So all the basic css/html/js questions they asked before they actually started with the coding part, I missed like 70% of it. I am a React developer so I don't work with vanilla JS that often, The interview was really easy though. If you have minimal algorithm knowledge and focus on JS/CSS/HTML you will make it easy. All the questions they asked you can find on google. Nothing out of the world.
My recruiter told me I was reaaalllly close to get it lol. I felt that.
