      Application

      I applied through a recruiter. The process took 5 days. I interviewed at Wowcher in Aug 2016

      Interview

      I reached the company through a recruiter. After almost a week I had a telephone interview about the company, the person that they were looking for and some technical questions regarding Java. They were really friendly and they asked me some further questions about my CV. Generally it was a positive experience.

      Interview questions [1]

      Question 1

      Some of the questions were about concurrency, volatile, synchronization etc.

      Java Software Developer Interview

      29 Jan 2021
      Anonymous interview candidate
      No offer
      Negative experience
      Average interview

      Application

      I applied online. I interviewed at Wowcher

      Interview

      1: HR round 2: code assignment. It's ok, no time limit, no hackerrank-ish feeling. Testing is appreciated. 3: technical interview with 2 senior developers. Again, felt like an interrogation. I didn't get one single question right (Spring security) and it's done, bye, thank you, next. Extremely disappointing experience. I don't recommend. Oh, and their webpage looks like garbage.

      Interview questions [1]

      Question 1

      Spring web (REST mostly), spring related questions.
      Answer question
