I need some guidance and suggestions before spending a lakh on interview call platform

Hi All

I’m a 3 year experience software engineer working in Indian product base company at 12LPA.

I need suggestions before going into this, I have been talking to the guys from interview call from weeks now, had telephonic and Google meet discussions from various people.

I have given the test and failed in advanced level (the questions are on algos which I never herd) and they asked me to give intermediate level test and this was like college level like asking complexity of 2 for loops and probability it’s really easier.

They are pushing hard for registration stating that they have limited seats approx 36 per month only.

Total cost - 1.2lakhs
20k discuss will be applicable as I passed the test

So it will be - 1,00,000 RS

Things promised-

\- 5-6 months of training
\- placement guarantee
\- money back incase of no placement provided you completed most of your assignments
\- mock interviews (general and company specific)

I have made up my mind like I’m gonna join, but I just wanna check with people if anyone has joined these courses or any thoughts if your friends or any pls share your experience.

Thanks a lot.
