Fiz uma entrevista na empresa Visa Inc. (Varsóvia, Masóvia).
Entrevista
At first I got mail about my experience, university degree and past employers. After that, I got invited to OA from react. After that, Technical Round, which I didn't pass.
Candidatei-me online. O processo levou 2 meses. Fiz uma entrevista na empresa Visa Inc..
Entrevista
First stage: Online assessment (The assignment was about implementing a simple React.js application)
Second Stage: A 3 hour long interview.
The interview itself has 3 stages: Design, Behavioural and Technical. Each 50 minutes long.
Design stage was horrible - the interviewer was late. He should've asked about overall application design and architecture but he only asked questions about JavaScript and security. If he saw me struggle and be silent for a couple of minutes, he wouldn't help me. He would just stare at screen or look at his phone. If I asked for hints he would just ignore. He also asked me to code a leetcode medium question 10 minutes before the end of the interview. I had no time to solve the problem and he just ended the interview. The worst interviewer I've seen so far.
Next stage was behavioural. They asked many questions about soft skills.
Final stage is coding. The interviewer was also highly unprofessional. If you ask for clarification they just repeat the question, instead of once again providing a hint. I got asked about a simple palindrome string but seems like the interviewer doesn't know programming and just asks questions from a list. They didn't even know how to call a function.
Overall the interview process is very poorly structured. Feels like the interviewer don't even have knowledge of the topic they are talking about. I didn't like any of the stages.
I didn't receive their feedback regarding the interview and got ghosted.
Even if I got offered, I'd decline the offer since the company is very poorly organized...
