Microknot Reviews & Testimonials
Aravind Nambiar's Review Sourced from Google
Worked with Microknot over a period of 4 months to build a financial simulation & visualization of supply chain activities. Microknot architect and engineers provided the framework, design & setup on Azure and the development activities. It was a great experience working with them!
Kel A's Review Sourced from Google
The EDI system that Microknot created was a little slow to start up due to the complexity of our system. But it's now reached a point where it's saving me time with our orders. The team were prompt in responding to emails & were a pleasure to work with.
Dave Philips's Review Sourced from Google
We have enjoyed working with Jag, Shaun, and several of Microknot's developers over the past 18 months. The Microknot team has allowed us to accelerate the time to market for our platform, translating to money in the bank and added scale to our internal development team without the risks, time delays, and costs associated with hiring new staff.Microknot's professionalism in managing our project has also lifted the game for our internal team. Not only have they delivered a great product outcome, but we've also learned a lot about different technologies and effective s/ware PM methodology in the process.The Microknot team have been responsive, easy to work with, delivered every sprint on time, and significantly contributed to guiding our application in the right direction.I can't thank the team at Microknot enough for their contribution to Biode, and I would not hesitate to recommend them to any business looking for a trusted development partner.

Priyanshi Verma's Review Sourced from Google
Unprofessional, Mentally Draining, and Disrespectful Work CultureMy overall experience with this company was extremely toxic. During my short tenure, I observed several deeply unprofessional practices that left a lasting negative impact on me:•Salaries were often delayed, without prior communication or explanation.•There were unexplained deductions in monthly salary, and any attempts to raise concerns were either ignored or dismissed by HR.•The HR department was shockingly rude. I personally witnessed employees being humiliated or emotionally broken when they decided to resign — some even left in tears.•No proper Full and Final Settlement (FNF) or professional offboarding process was followed. It’s like once you resign, you’re treated as if you never existed.•Even after resignation, the company continued to send intimidating and threatening emails and begging for small amount of money like 20k, showing a complete lack of empathy — especially towards people who were already in a tough personal or financial situation.If you’re considering joining, please rethink carefully. Make sure everything is documented in writing — verbal promises mean nothing here. A company’s real face shows not when you join, but when you try to leave. And unfortunately, this one shows zero professionalism, zero compassion, and zero respect for employees.

I took 4 rounds of Interview for US IT Recruiter position..1st is virtual, 2nd round is In-person, 3rd and 4th are telephonic...They did not give any feedback.Worst experience, please don't attend interviews.waste of time
varsha kaushal's Review Sourced from Google
One of the worst organisation I have ever experienced . Exit process is worst moreover company doesn’t respond on your final f&f queries and literally one has to chase to get their full n final payment. Depending upon clients requirement organisation and their leaders push their employees and even salary is deducted if it is not billed as per clients need. Pathetic to be honest. Lala companies are doing better than this in country.
