Interview
Applied through referral. Got a call from HR for scheduling interviews.
1st Round : asked questions on programming linked list and arrays and bit manipulations

Question 1
1. Program to find sign of number using bit manipulations.

Good. Technical details were discussed clearly, together with my past projects and relevant domain knowledge. The interview was well structured and focused, with questions that allowed me to present my experience, technical background, and problem-solving approach in a coherent way.
Posso dizer que num geral positiva, processo rápido, em uma semana foi realizado. Perguntas de nível médio, bem técnicas mesmo e assertivas. Entrevistadores simpáticos, duração longa de entrevista, mas foram ok.
