Kry Full Stack Software Engineer interview questions

My overall experience was very positive. All the interviewers were very cool which helped me to few comfortable during the whole process. My process took 4 steps, about 4 to 3 weeks. First step was a call with recruiter, second was a 1 hour hangout interview with Engineering Manager, the third step was a code challenge to be done using Vert.x. fourth step was a code review with 2 software engineers. I didn't pass to the next step.
