Cyber Sapient interview questions

Don’t waste your time Unprofessional and disrespectful I applied for the position of Senior software engineer, they sent me a small test app to create, I spent a weekend on that, after that they told me I passed and set up an interview after 2 months, which was weird but ok, took the day off to attend the interview, and then nobody showed up, no cancellation, no rescheduling, just decided not to attend the interview that they set up 2 months ago, I contacted them and got no response.
