Interview
I applied to the Data Scientist – Entry Level 2024. They gave me a Hackerrank assignment, which was easy to complete. 1 coding question and 1 DB question. For the coding question, they gave me sample print statements to compare against. This was for the sales team and the one-way video interview asked questions about being a sales person and having relationships with clients, which I had no prior experience. One-way video interview was on Knockri's platform. Got rejected before I was able to submit the one-way because I took too long with both steps even though I still had 5 days with the second step. They gave me 2 weeks for the Hackerrank and 2 weeks with the one-way.

I applied online. The process took 2 months. I interviewed at IBM (Atlanta, GA) in Nov 2019
Interview
A couple rounds via zoom, and then they flew us all out to a super day. Absolute joke. Nobody had any idea what was going on, the interviews were a joke, and I left with a worse gut feel about IBM than I entered with

Interview
Me foi pedido um teste prático que deveria ser feito em python. Esse teste consistia em construir um classificador de sentimentos para Twitters em Português e colocado em um domínio online, seria interessante criar um dashboard com essas informações. Eles pediram também para esse classificador analisar em tempo real os Twitters. Se fosse satisfatório eles iriam realizar a entrevista técnica. Fui para a entrevista técnica onde me fizeram uma série de perguntas técnicas de como foi feito o desafio e também a respeito de estatística e conteúdos teóricos( por exemplo, o que seria um recall e em qual situação ele seria utilizado), Além disso foi feito uma entrevista técnica em Inglês ( me pediram para explicar o seria um falso positivo).
