* Unprofessional recruiters - They call you without prior notice. They do not respond to your email or phone calls. If you don't wish someone to call you, why share your number? I couldn't reach out to my recruiter when I had serious technical problem during my interview. Whom am I supposed to reach out to? * Scheduling of the final interviews was extremely bad. You can't expect people to give final interviews with just 24 hours of notice. The recruiter disappeared after I could not schedule my interview immediately. * The final interview was extremely hurried (after one of the interviewer could not connect to the interview for a good 15 minutes). They kept on pushing me write code before I could come up with a solution. The difficulty of the interview also varies wildly.
