I applied online. The process took 4 weeks. I interviewed at RHOMBUS POWER (Kingston, ON) in Jul 2020
Interview
After applying for the company the first round was a challenge round in which i had to write a program to scrape data from amazon. The next step was an zoom interview with project coordinator and a UX developer in which questions regarding background, sql and python were asked. After getting selected in the 2nd round i was called for a CTO round which was also the final round. In this round also questions regarding background and data analysis were asked. After which i received a call from interviewer the same day at night congratulating me for passing the final interview and i was offered the role and informal discussion regarding the pay, role and benefits happened. Next day i got a call from HR regarding the queries i had about role and was asked to send a mail after the call if i accept the offer (which i did). 3 days later i got a mail stating that i have been rejected and that they moved on to the suitable candidate. If i was not a suitable candidate then why did i receive a call saying that you have been selected and discussed everything from paycheck, taxing, probation period to shifting date, etc. The only thing i would like to say to Rhombus is that don't give hope if you want to keep someone on standby while interviewing other candidates( you can mail them once all the interviews are done). Secondly, if you are giving a verbal offer than do standby it. My overall experience was very bad with company starting from 1st round in which the interviewers were laughing on my answers to getting an offer and getting rejected in 3 days gap.

Interview
They asked for Onsite Interview without reimbursing anything. The panel is very rude and some of the recruiters too. During hackathon, they will ask to complete the coding without using AI, not even for boiler plate. in 3 hours, you have to complete the project and host it, everything on your own. Even if this is the last company, don't go for it.
