Interview
Especially if you're looking for cheap contractor labor from South Asia, this startup might suit you. But if you're seeking solid career growth and professionalism in the telecom/cloud industry, don’t waste your time here because it will take 2 months at fastest. Just take a look at their employees on LinkedIn and you’ll understand the company culture immediately.
The hiring process took more than two months. They were actually the ones who initially contacted me. After the recruiter interview, I went through a technical interview and was then given a 3-day case study. It wasn’t extremely difficult, but it was definitely time-consuming. To stand out, I didn’t just complete the assignment, I also prepared a demo, a presentation, and a detailed technical report. I even designed a web interface for it.
The case study presentation went very well, and they moved me to the next stage. The Hiring Manager explicitly told me that the team was impressed and wanted me on board. After that, I had a chat with the VP. During the technical interview, a senior engineer had mentioned a specific stack to me, so I asked the VP about it. He claimed I had misunderstood and that such a thing didn’t exist. That was my first sign of poor internal communication within the company and the attitude was rude.
One week after that chat, I sent a follow-up email and was told there were still ongoing interviews with other candidates. Eventually, after more than two months since the first interview, I received a generic rejection email saying: “Unfortunately, the position has been closed.”
Excuse me, what?
Didn’t you properly plan your budget or define your team’s hiring needs? This is a clear sign of poor coordination between PMs and Hiring Managers. What really frustrated me was not the rejection itself cause I would completely understand if they had simply found a better candidate. But making candidates spend days on case studies and dragging the process on for weeks for a position that apparently might not even open is incredibly disrespectful.
It honestly feels like all my time and effort were wasted. Still, I’m also glad I won’t be working at such an irresponsible and unprofessional start-up. If I had read the Glassdoor reviews beforehand, I would never have agreed to proceed with the process.
This was a waste of time. Candidates are asked to complete an unpaid assessment that requires significant effort, only to be rejected without any feedback. At a minimum, feedback should be provided given the time investment. As it stands, the process gives the impression that candidate ideas are being used without proper consideration or transparency. Additionally, the interviewer appeared disengaged and mentioned that telecom is “not fun,” which did not leave a positive or professional impression of the role or the company.

It was a complete waste of time!
Don't make hopes and keep looking for other companies in parallel if you're giving interview at NG-VOICE!!!
I applied for a DevOps position in February end and got the first interview in March.
1st Round (HR Interview) : The HR was nice, he said I will get back to you within 24Hrs to which he answers after 3 days. No problem it happens I didn't mind that decision.
2nd Round (Hiring Manager) : This was Genuinely the best round I had. HM was really supportive he asked fews question on my resume, monitoring resources and my ambitions. I passed the round and got the case study the next day.
3rd Round (Case study): It was a 5 day case study, Questions were asked on like create a cluster, deploy a db cluster etc. I finished the case study in time and also made demo videos which took me 24hrs of continuous work.
After 3 days the HR mailed that they are searching a date and time to present it. I was like ok that's my chance to prove myself. I was confident enough to tackle this.
Case Study Presentation Day: The presentation went exceptionally well than as I expected. I gave all the answers, showed my though process and had a great discussion about my resume and the different departments I have worked with.
I texted HR after 2 days about the result, he said I will get back to you by weekend.
The HR texted on weekend that they had to postponed the results because some people are left to present their case study. I was like "Ok fair point" ( But I was but optimistic that I can clear this round and can go to the last and final C-level Interview).
A week after the HR called me directly and said that, they have to close the position because the management people changed the requirements.
I was so pissed! A complete waste of time!
I contacted few more people from linkedIn and reddit who gave interviews and got the same feedback from them.
