    Senior Consultant Interview

    Anonymous Employee in New York, NY
    Anonymous Employee in New York, NY
    Application Details

    The process took 3+ monthsinterviewed at Informatica in July 2011.

    Interview Details

    The entire interview process started in first week of May with the HR contacting me directly. I don't remember where/how i applied but i believe i found an opening on indeed and applied directly with the company.

    First, here is a little background about myself. I have about 7 years of total experience in DW/BI and most of it has been on Informatica Power Center client.

    After the initial background discussion with the HR, she said i will have 2 technical interviews. The interviews were scheduled and re-scheduled multiple times. I understand that most of the folks who conduct interviews are busy with their assignments, but so am i or any other candidate so i was a little disappointed with so many re-scheduled interviews.

    Anyways, the first 2 were pure technical interviews. You can't pretend to know something or prepare for the interviews. Unless you have hands on experience you can't answer. Few of the questions are as below

    1) Informatica 7x, 8x, 9x architecture, (need to explain about SOA etc)
    2) Can you install multiple instances of powercenter on same host? if you can, then how will you invoke different instances from a client since you provide same host name? configuring different ports is not the right answer.
    3) Can you invoke a mapplet variable from a worklet? and vice-versa? Can you use a mapping variable inside a mapplet? and all such combinations!
    4) different types of partitions. In depth usage of each partitions and different scenarios(need to provide examples where you have used them in your project, not just the concepts)
    5) dynamic cache, and dynamic partitioning questions
    6) Configuring grid on informatica server, configuring domains, pmrep command usage etc.

    I am not gonna get into more details, basically they are gonna ask everything and anything! These guys know the product in and out, so be prepared for anything! They were very keen on my knowledge of Powerconnect for Tibco/SAP etc but i had never used them in a project even though i had working knowledge.

    They absolutely didn't care about my knowledge in UNIX, shell/perl scripting, DW/BI knowledge, Meta data management or data modeling. All they were interested was Informatica products experience.

    Anyways, I did clear both the technical interviews. I had 3 other interviews with 2 VP's and a Regional Manager. Again, all these interviews were re-scheduled multiple times dragging the whole interview process to over 3 months. The VP's and regional managers were more interested in my consulting background and softskills and just a high level understanding of my informatica knowledge.

    I did clear all the interviews. The final interview was with a VP face to face in their NY office.

    Reasons for Declining

    After almost 3 months since the process started i finally received an offer. The offer was substantially lesser than what i was expecting ( the base component) . In the meanwhile i got better offer with one of the top consulting firms. I was definitely inclined to join informatica, but they was not much room for negotiation. They were willing to bump up 2.5k above their previous offer, which was still substantially lesser than the other offer i had in hand.

    The other offer i had required no travelling and better pay, more personal time in my life! With informatica professional services, you would travel ALOT! and i expect them to pay for that inconvenience.

    Regarding all the other people talking great things about Informatica benefits, they have either never worked for a big company or this is their first job! The other offer i got has better benefits than Informatica in every single category Healthcare/Vacation days/401k/bonus. Informatica offerred me NO bonus? really? for a high growth company, no bonus? common!!

    Anonymous Employee in Bangalore (India)
    Application Details

    I applied through college or university. The process took 3 daysinterviewed at Informatica in June 2012.

    Interview Details

    The first question, was explaining about work profile which was good start to demonstrate technical capabilities and make good impression of expertise in domain and technologies. ( this is what we already write in our resume/profile, but it was chance given to explain out yourself).

    Next question was to explain out current project architecture and implementation on big board. Here, had interactive session for 5-10 mins on process flow, different pros and cons of architecture design and explaining out how this design works with actual use cases. ( This works out to be good demonstration for what currently doing, so started with explaining project architecture SOA based layered architecture, emphasizing more on J2EE core design pattern, GOF design pattern for creational, behavioral and structural, also talking of solution components and how they are integrated like EJB, Webservices, JMS, Database, Quartz batch scheduler.

    Next questions was sort in debate mode on clustering (application running on multiple server) and how application works. More specifically on batch scheduler running in cluster environment. Expectation was high level explanation how Quartz scheduler handlers cluster deployment.

    Next question was on making MQ messages transactional in synchronous communication environment. Let's say I have an application which need to send out messages to two databases oracle and sybase, part of record is written in oracle remaining part of same message goes in sybase, so let's say if sybase transaction failed then how would you roll back whole transaction so that data in oracle is not inconsistency with sybase database

    Interview Details

    I applied through career fair. Got a mail after 2 months that they are interested in taking one hour phone interview, send availability for one 60 minute phone call. I replied them back with suitable time for the interview. After that radio silence. No mail, no call. I followed up twice to check if i am still considered for the position. But didn't receive any reply at all. It was clear to me that I am rejected,but why? This is absurd. How can they reject without even taking interview.
