      Software Engineer - Data Mining/Data Analysis/Machine Learning Interview

      4 Oct 2019
      Anonymous interview candidate
      Sunnyvale, CA
      No offer
      Negative experience
      Average interview

      Application

      I applied through an employee referral. The process took 2 months. I interviewed at LinkedIn (Sunnyvale, CA) in Jul 2019

      Interview

      Invited to interview on-site in Sunnyvale. Recruiters were EXTREMELY slow to schedule the interview and even worse following up afterwards. It took them a full month to give me any response after my on-site. Also, all 6 of my interviewers in the 6-hr interview were Asian men. Not a good look, LinkedIn, especially when you're recruiting a female engineer.

      Question 1

      Only one easy/medium leetcode question during the coding module.

      Software Engineer, Data Mining/Data Analysis/Machine Learning Interview

      25 May 2019
      Anonymous interview candidate
      San Francisco, CA
      No offer
      Negative experience
      Average interview

      Application

      I applied through an employee referral. The process took 2 months. I interviewed at LinkedIn (San Francisco, CA) in May 2019

      Interview

      The interview process was positive but the Recruiter experience is negative. I was referred to a Data Scientist position but recruiter switched me to this position saying I don’t have e-commerce experience. She told me to prepare medium to hard coding questions so I took some classes and learned data structure and algorithms. And I postponed my interview and prepared two months to find that the position is more towards the data scientist position instead of software engineer and they tested me statistics and not much coding. The recruiter’s Instruction is really misleading and she refused to admit that after the interview and blamed me for poor performance in the interview.

      Positive experience
      Average interview

      Application

      I applied through an employee referral. The process took 4 weeks. I interviewed at LinkedIn (Sunnyvale, CA) in May 2018

      Interview

      I applied through employee referral. First had to clear a phone screen which was a mix of problem solving (Leetcode Easy) and conceptual questions on Machine Learning(just algorithms and how they work). I heard back from them the same day. Then I was called onsite, where I had to 6 rounds with 2 engineers in each round. The Algorithms and data structure questions were from Leetcode Medium. It's more of a discussion rather than an interview. The entire process was fun. But they took 2+ weeks to give out their decision.
