“Good process, helpful HR. I couldnt finish stats, I prepped hard but stalled during interview. Be calm and cool. Practice more and get strong in stats and rv fundamentals”
“The overall interview process went smoothly. My recruiter was friendly and communicative, and flexible with my schedule (I was traveling and had to split up my interviews). I received feedback relatively quickly after each round (within a few days - I often had to wait longer with other companies). No surprises, the recruiter clearly described the type of interview for each round.”
