I applied online. The process took 2 months. I interviewed at Dejero Labs (Waterloo, ON) in Oct 2020
The HR sent me a survey that took approximately 30 minutes and has 2 parts (problem-solving piece and then rating section for them to gain more insight into my preferences and work style). I was then asked to schedule a time and date for a phone interview that took around 40 mins with the HR asking general questions regarding my work experience and resume. Once you have passed the phone interview, you are then invited to complete the Technical Take Home Assessment. The intent of the assessment is to help them get a better understanding of your overall technical knowledge and its applicability to the role you have applied for. The take home assessment should take a few days to put together. After, you are then invited to a Technical and Behavioural panel interview with the HR, Senior Technical Support Analyst, and the Technical Manager. They will ask you high and low level technical questions along with behavioural and scenario based questions. After passing the Technical Panel Interview, you are then invited to an interview with the Technical Manager and the Director of IT and Infrastructure. They will ask you some more technical questions along with behavioural questions. This stage is a conversation with the Technical Manager and the Director of IT to get to know you better and if you are a appropriate fit for the role and Dejero. Once you have passed the final stage, you are then required to complete a background check and provide professional references to the HR. This process can take up to a week.

Very long interview process consisting of 4 rounds and none of them being technical at all. You basically seat there and talk about your imaginary project ideas. overall process takes 1.5 months and lots of background checking. Your reference will receive 30 minutes worth call !

Interview process was very smooth, but the HR repeated the same questions she asked during the phone interview as well as in-person interview with HR which I thought was waste of time.
- Questions were very technical from the technical team. good questions.

I applied online via LinkedIn Easy apply for the Senior software developer connectivity position. First response was within a week. The HR (People & Culture) team was very prompt and professional throughout the process and quick to respond to all correspondence. Following initial phone screen a take home assignment was provided and some time to complete it within. I spent a significant amount of time on it, but I wanted it to be very clean and polished. An in person interview was quickly scheduled following the assignment being delivered. The in person consisted of some senior developers and HR. Management was present for a portion of the interview. I received a verbal offer for Software Developer the same day as my in person interview.

Standard HR stuff, technical interview had a take home assignment. The take home assignment is relevant to the job I applied to, it allows you to demonstrate things that you don't normally get to in a "normal" whiteboard interview.
- Take home assignment, develop a tcp server/client with specified functionality.

I applied via LinkedIn from overseas. My interview process was much more drawn out than for people who applied while living nearby - probably because the 5-hour time difference makes it hard to arrange things! An initial non-technical phone call was arranged soon after I applied so I could find out more about the company and the role. There was a plum.io aptitude test and and an online questionnaire (the latter has since been replaced by a take-home coding exercise). This was followed about a week later by a 90-minute Skype interview with an engineering manager, where my technical knowledge was tested and I got to find out more about the company's development process and technology. A week after that, there was than another 90-minute video call with a technical member of the senior management team. This was less focused on technology and more on the company's plans for the future and whether I was ready to move to Canada.
