Highly unprofessional.The process took 4 weeks.I applied through AngelList.In 2-3 days got a phone interview call from CEO , he asked about my background and projects(15mins).Next day i got a hackerrank challenge,it was pretty easy (MySQL and 2 coding question).In 2-3 days i got a call for onsite interview.It was conducted by product manager,software engineer(there is only one technical guy in team) and CEO(again projects and technology used),I was surprised when he asked do you have a MAC which you can use for company project(Are you serious????????),discussed salary,i was told in 4-5 days they will get back to me.After 4-5 emails they told me to get 3 references.Once i gave the references they were never contacted them.They are so unprofessional that they never responded to my emails afterwards.I would suggest not to waste time by interviewing at this unprofessional startup.
