Don't waste your valuable time and energy for this pathetic company and their third class "one tech" hiring process. That's pathetic for candidates and in the end, you will just more stressed after waste of effort.
They will just keep you in their so called "pool" of "qualified candidates", their match calls are just jokes, they are actually another rounds and rounds of technical interviews and even if you do well, you will not be hired, because they don't want to hire people more intelligent than them. Period!! They are worried and insecure about their jobs as you might take them one day from them.
Don't waste your time even for interviewing them as you will never get your interview's feedback even after multiple follow-ups with recruiters. It's not just me who is saying that, you can read other reviews as well.
If candidate has already cleared all interviews which they refer as "Power Day", then why to bring 5 people interview panel for a match call? Match calls are just for supposed to be between just hiring manager and candidate, but there are no rules for that. Because you just want to waste people's time and don't want to hire somebody more technical and skillful than you.
Don't waste your time, energy, resources for this terrible terrible company, otherwise you will always be sitting in their pool and stressed forever. Better go find something else which will hire for a specific role and position which you will know from Day 1 and would provide you clear picture in end to end hiring and on-boarding process!!
