Is edtech really scam

Hello all , Did anyone availed the course from bosscoder? I am a data engineer and planning to upskill myself on DSA . Any suggestions?

Have any of you tried bosscoder or any other learning platforms that guarantee placement? How true is it ?

Context: Imma tech consultant at Salesforce and I am yearning to switch into a more techie role and being a ADHD junkie my only practical way is to get into sde program/course. Now my question is have anybody tried Bosscoder for their SDE program? Or there is better alternatives. Worth noting that I am looking for placement support as well. TIA.

Do people really get a job post completion of upskilling courses?

I was thinking to join data science course in scalar program. Quite expensive program hence please help me to say whether course is worth for beginners wrt course ,teaching and projects in the curriculum. Also whether they have a job placement after course completion and whether actually we get jobs . I am already 9 years experienced but from database and devops background not data engineering. If anything better course then scalar along with placement ,that also can be advised.Thanks in advance
