      Software Engineer Interview

      Jul 11, 2021
      Anonymous Interview Candidate
      Bengaluru
      Declined offer
      Positive experience
      Difficult interview

      Application

      I applied through other source. The process took 1+ week. I interviewed at Ecolab (Bengaluru) in Jun 2021

      Interview

      I am an immediate joiner(left previous company just like that as I got pissed of with the people handling). 3 technical and 1 managerial round, on average 1 hr per round. To be honest the interview process was smooth. Took 12 days for these and asked me to join immediately. As job seekers we'll be attending several interviews. Got 3 offers in 2 consecutive days. I chose the good one out of these(Didn't negotiate package to any of these company on the fact that I am expecting offer from other company as I have seen several companies trying to take advantage of me being left the job already, so I asked package like this is the 1st company I am getting offer). So I politely told the hiring HR sorry I will not be joining you're company in the morning and last night only I got 2 company offer. He's getting emotional and talking about my personal things. I told him don't talk about my personal things. You want to onboard good candidates and I want to join good company, that's it and he cutted the call. In between he asked one illogical question you didn't told you're parallely attending other company interviews which made me laugh :) as if we should attend only one interview Don't be too emotional you're doing business
