I got to know about a job of junior data analyst in machine learning. I was interested and applied for the job via monster. The job required a preliminary teaser task problem to be solved, sent along with resume, cover letter. I sent them an average intuitive solution for the task( Since the task was marked optional ). After 4 weeks, I got a call for a telephonic Interview. The interview lasted for 45 minutes. The Interviewer asked background questions, project experiences and 2 very simple algorithm questions. I correctly answered the questions with alternative replies. I was further told to fix the teaser task and resend them the solution(which I did send them ). They were supposed to get back to me within a week which they failed to do so. 1 week later, I had to email HR to ask them about the feedback. They sent me same blah-blah answer along with good luck reply saying there were too many great candidates with great degrees & experience who outbid me ;) To sum up : I ended up wasting my 12-16 hours on a statistical test . The final feedback is very disoriented and indifferent; mentioning nothing about my solution, interview process. My take: The process of hiring is non systematic. The HR complains of lack of time spent in telephonic discussion as reason of their inability to screen me out , there by resume, qualification and experiences being used as deciding factor. I personally felt the interviewer didn't have domain knowledge; lacked technical depth of algorithms.
