Applied through a recruiter agency. Got a email response quickly from recruiter stating I had a phone interview. Two days later was called by two hiring managers. Call went well. Was later told by recruiter that they want to do a onsite interview. This took place a little over a week later and it was a terrible experience. Initially met with HR and that was fine, standard intro questions and review of company culture and all that. Was later informed that I will be meeting with three separate people in separate interviews and they would be administering a series and word problems and challenges. This was not mentioned whatsoever by the recruiter and had no clue what I was getting into nor had time to properly prepare and also was told it would take 1 hour, actually took over 3 hours. First interview with interviewer 1 was fine, nice guy, personable, had good dialogue and could answer all his questions. Lasted about 45 mins. Second interview was with interviewer two was the most humiliating experience I've ever had in an interview. Extremely condescending individual who would actually smirk and try not to laugh at some of my responses. He issued three challenges to me, a hand written equation to solve, a SQL question about syntax structure and execution sequence, and algebraic word problem. Mind you, I have not done this type of math in years and had no warning that this would take place, so I failed the math questions as I couldn't read his writing and I guess I've become lazy and rely on excel now to do my math. The SQL question was fine as I know SQL. In the third interview I was given an ad words challenge about purchasing clicks to get a desired revenue ratio. Again, no where is the job description did it mention anything about adwords, ad purchasing or related activities so I was not prepared for this at all and not as sharp with ad click math as I should be and failed this one bad as well. Overall, I walked into a massive trap and left feeling extremely stupid. Be warned, be prepared.
