HARMAN Technical Lead - Java interview questions

Reached Bengaluru office at 10.30( scheduled interview). Waited till 12.40 for them to call me( this is even after i told them i should leave by 1 pm). Interviewer asked few one liner questions like sql selecte queries, one prgram to print in the following format a b c d e f asked if i had used maven thread life cycle, how to create threads json structure asked about singleton what is it.. before i could answer or explain he would stop me and go to next question. Interviewer was not at all interested in listening answers. I wrote program but he wanted what ever he googled answer!! In 5 minutes one can only think of different approaches to solve a problem unless one can mugged it up like college student!! Few more questions like one liners again. Better take telephonic interview. Very bad experience. Not at all professional. I have 12 years of experience..this was the very unprofessional interview process i ever attended. Guys please don't waste someone's time. Better conduct telephonic interview than face to face.
