Ho presentato la mia candidatura online. La procedura ha richiesto 2 settimane. Ho sostenuto un colloquio presso CGI (Halifax, NS) nel mese di mar 2017
Colloquio
First, I was contacted by technical recruiter and she arranged for an interview. The interview was code test followed by interview. The interviewer sent me webex link, and after joining he gave me control to his system. A use case was written and I was asked to write code for it. The use case is as follows.
There is a list of Employee objects and Phone is an instance variable object inside Employee.
1) When we are printing the employee object, Phone needs to be printed in a specific format
2) Sort the employee objects inside the list based on joining date descending order
3) If we pass list of employee objects and name of employee to a method, it should return the employee object if it has that name.
After this coding test is completed they asked technical questions.
