Phone interview was very basic. In person interview consisted of 2 interviews, one on one. The first one was terrible, the woman was absolutely rude and very clearly trying to throw you off your game. The second individual was extremely nice, even when he threw a logic question at me, which I didn't get (and yes, they always present you with at least one logic question so be prepared).
Be aware that because you have to deal with difficult clients, the interviews are somewhat rigorous, and the interviewers try to see if you can withstand rude individuals. If you like that kind of environment, then go for it.
This definitely wasn't for me.
Also, you are expected to give up some of your weekends in order to ensure upgrades are completed smoothly. This would be okay if they were adequately compensating you, but they only pay around $50K which is too little relative to the amount of hours they want you to put in (7am-7pm).
HR reached out to me with a generic email 3 days later with a NO.
A tip - make you sure you work extensively on the questionnaire you are required to send out before the interview. It has numerous questions which take a couple of hours to answer thoroughly. And they use those very questions, as well as your cover letter, to assess you during the interview.
